Hey yall. Thought I would post some pictures of my board. It is modeled after David Gilmours Pete Cornish Board. This is the 2nd version of my project, this one is going much better than the last. I should be done in another month or so.
Power: AC Power entry modules feeds 5 transformers. Two are for the tube drivers, one is for the mistress, and there are two 9v for the FX and LEDS (kept completely seperate). They are Cincon units and are SILENT. There are 4 external 9v jacks on the back for external FX
Connections: Every wire (except pots) is shielded and will be grounded as well. All jacks are shielded. Each AC connection is crimped, soldered, heat shrunk and wire tied. All wire terminations are heat shrunk.
Dimensions: 36" W, 25" deep, about 8 inches tall in the back. I just weighed it for the first time, without the back, and its about 20 lbs. I figure it'll end up around 30 once its done.
LEDS: Each panel is illuminated with one or two blue LEDs for backlighting. The indicator LEDs are RED and one appears above the stomp switch and on the appropriate panel.
Fans: Two AC fans will be installed incase of heat problems (not really necessary but cool) They have an on/off switch too.
Switching: The signal is true bypassed however there will be IC buffers placed strategically where needed. They will not be overused.
Shielding: The entire box is painted with a special EMF shielding copper paint. The power entry module also has an EMF filter.
Signal is as follows and is a marriage between Gilmour's Animals/Wall era the the PULSE Rig
Input (A/B toggle)-->
Split to Signal Chain, Tuner and Talk box Out
Colorsound Power Boost-->
Skreddy Lunar Module-->
Compression (CS2/Dynacomp toggle)-->
S/R for Wah
S/R for Whammy
Vintage Tube Driver (clean boost)-->
Distortion On/Off-->
Distortion Select (Select between: BYOC Triange Muff (w/EQ) and RAT2. There is also a switch on the RAT panel to select an external S/R for a different Distortion in place of RAT..also with dedicated EQ)-->
Vintage Tube Driver 2 (Overdrive)-->
Univibe/Phase 90-->
Howard Davis Modded Deluxe Electric Mistress-->
Boss CE2-->
Boss TR2-->
EQ (w/ on/off stomp switch)
Final EQ (on/off toggle)
Volume S/R
From here, the signal is then split again 3 ways. The analog signal goes directly out to a mixer, then the signal goes to delay switch 1 and 2 (if selected). The delays (Ibanez DE7 and TC Electronics DTwo) are set to a full wet mix, and their outputs are sent to a mixer. The main signal is then blended with the repeats in parallel. this way, just like gilmour, the analog signal never travels through the digital delays.
A leslie simulator completes the chain.
The board, so far, has proven to be pretty damn quiet. I have had issues here and there, but once they are resolved, its great. I am very excited about completing this project, as it has been a long time in the making.

Questions, criticism, whatever, lets hear it. If you think that the basic cornish style is ugly, then please, you dont have to let it be known. I think i have done a damn good job so far. Yes i know that its not nearly as advanced. Yes i know that he does not use true bypass. I have tested many methods and it seems to work damn good for me. Am I pete Cornish? hell no...im a gilmour nut who likes to build things. anyway, enjoy, i will keep it posted, and i'll keep this page for my problems/questions etc. Some constructive suggestions would be great. thanks!
....what...can...I...say...
Very impressive board! Lots of options, well thought out. Looking very good!
Any chance you can share the dimensions and weight of the board?
thanks!!! i'd say there is well over a years worth of planning. this board is all about options, options options. They are there.
I just updated the specs with the dimensions.
I also use a seperate powersupply for the LED's. Lots of LED's to be fed ;)
Do you have a brightness control? I plan to have a simple pot to control the voltage to the LED's. That way I can turn the brightness up of the LED's in a well lit room, and turn it down again if I'm using the board in a low lit room.

Thanks for adding these. In metrics that is roughly 91 X 64 x 20 Cm, 10Kg now, 15Kg when finished.
That's a BIG board ;)
You are using way thicker wood than I am using. Do you feel comfortable (/y numb....) stomping the switches?
yeah i thought about using a pot to control the voltage for the LEDs, and I still may do it. It is big yes, but think about how big a board containing all those pedals would be. roughly the same size and weight...eh who cares. My tiny little peavy classic 30 weighs a lot more i know that!!
and yes, i can stomp all over it no problems.
Wow! Just...wow!
In picture #6: What are those switches and jacks for and where are they located? A damn awesome 'board, by the way! ;D
thats the back panel
It has the following:
Main out
tuner out
talk box out
Distortion Send/Return with bypass
4x 9v External power plugs
Stereo S/R w/ Bypass for the following :Delay 1, delay2, rotary sim, wah (with switch to reverse the signal for "echoes") and whammy
input A and B
i thought i might update this thread.... i have a few pics but not many.
I had to back "pedal" with the power supplies. I am now going to use a large custom transformer with many windings into about a dozen highly filtered and regulated custom power supplies. The only pedals that still require AC are the two Tube Drivers.
Also, I think I am going to take out all the 3PDTs and use a Millenium2 bypass circuit instead, this will make switching the two indicators per effect a lot easier.
Other than that, I have accomplished a LOT. So far the following FX are gutted, modded, placed on the panel and wired for signal, power and ground:
Tube driver 1 and 2
MicroVibe
Phase 90
TR2 tremolo
CE2 chorus
Skreddy Lunar module Fuzz
Colorsound PowerBoost clone
BYOC Triangle Big Muff clone
electric mistress
buffer
Wiating on parts to complete:
RAT, CS2, Dynacomp, 3x GE7 Eqs
the power transformer is currently being built and has 14 windings:
8x 12vac @100ma (individual FX)
3x 12vac @200ma (one tube driver/3xEQs/Vibe-phase-trem)
1x 12vac @1a (external power jacks)
1x 15vac @100ma (mistress)
1x 24vac @200ma with Center Tap (tube driver)

good to see an update!
One thing I didn't know a couple of hours ago when I send you the PM, my mil2bypasses are giving some issues. I've had quite some issues during the first design/test phase like over a year ago. The BS170's died too fast. Now I took my stash of 'ready' footswitches and it appears the issues have returned. Tested 5 now, 2 are dead. Further investigation required, no need to panic :icon_mrgreen: but I though it'd be good to let you know.
That build is monumental! You should be hella proud to have gotten this far. Do you have some cool shock mounts for the tubes like Pete likes to use? By the way, does anyone know what the core switch is that Pete builds those wooden doughnuts for? They must be pretty formidable on their own. (and pretty honkin' big too!).
Besides the costs for the actual FX, what's this puppy going to cost? Less your labor of course. I'd guess $1K~$2K USD.
Just to help signify that you've arrived, I'd offer to roadie for your first gig, FREE! But I'm getting too old and feeble to even pick out the Brown M&M's let alone tote that behemouth up a flight of stairs.
Best of luck with your fabrication & wiring chores still ahead. All your pre-planning seems to have been worth every minute of it. Keep us posted on your developments,
NG
Hello,
I have made much progress! While a lot has changed, a lot has also been done. Almost every effect is ready to be wired, and the switching and power system is in the final design stages. I went back to 3PDTs. I just added the fans, they are more for Mojo than anything, but will also provide nice airflow across the 17 some PSU regulators, which will be on two large PCBs stacked on each other on the back panel.
The backlighting and indicator LEDs will be powered by two individual LM317 adjustable PSUs with dimmer knobs. The plates still need to be cut to cover the bottom of each panel.

(http://i23.photobucket.com/albums/b379/sjaltenb/boardjan09005.jpg)
Here are some pictures, and the final signal flow is as follows: Buffers will be added where/if needed after everything else is done.
Input A/B
Buffered Split to Tuner and signal chain
Colorsound Power Boost
Skreddy Lunar Module
Compression CS2/Dynacomp with A/B/A->B 3way rotary
S/R for Wah
S/R for Whammy
Vintage Tube Driver (clean boost)
Distortion On/Off
Distortion Select between BYOC Triangle Big Muff and GGG RAT2. each has dedicated GE-7. RAT can also be toggled to external S/R for external drive pedal.
Vintage Tube Driver 2 (Overdrive)
Voodoo Lab MicroVibe/BYOC Phase 90 (toggle)
Howard Davis Modded Deluxe Electric Mistress and LPB1
Boss CE2
GE-7
S/R 1 for Rotosphere with line level adjustment by Adjusticator
S/R for Volume Pedal
The signal is again split 4 ways: The delays all have the dry signal removed, and are set to 100% wet to allow the mixer to control the repeat volume. The dry signal will also have a toggle to allow for the removal of the dry signal altogether to check repeats (ala David's real board)
1) Dry signal
2) To PT-80 delay
3) To Delay S/R1 w/ adjusticator (T.C. D-two rack delay)
4) To Delay S/R2 w/ adjusticator
The 3 delays will then be mixed back together in parallel with a GGG MiniMixer and that final signal is buffered and split to output 1 and 2.
More to come soon!!! a big thanks to everyone who has helped and put up with my questions along the way!!! It is very much appreciated!!!!!!
This is fantastic.
Looks great! Maybe I'll finally add CPU fans to my board.
Ever thought about putting some of those enclosures up for sale to help pay for this project? :icon_lol:
looking really good!
Any estimate on how much time you need to 'finish' it?
if i had all the parts I could do it in a weekends time. I just dont have all the parts ;)
how is yours coming???
designing the pcbs for the power supplies and adjusticators and 3pdts has been the worst part because i had to learn how to use eagle. im getting there though, its just a slow process. i imagine realistically that it will be up and running in a few more months time :icon_rolleyes:
its really hard when you dont have an electronics shop in your town, everyhting has to come from online, every resistor.
Ah, that's why I make sure I order a value-pack of common components now and then. That way I rarely run out of basic parts. Most of my stuff comes from online shops as well.
I've had a busy two months with a holiday in Egypt and, most of the time, busy with moving to my new house. Yesterday I 'finished' the DIY-room, so I think I can get back to DIY-ing pretty soon ;)
This thing is AWESOME! And this picture really cracked me up:

dude, i'd be toast :)
cool to see my work in some thing like this. looking gr8 m8
hahaha yeah that picture is kinda funny. good thing im in college and the girlfriend just laughs cause she knows she cant say anything :icon_mrgreen:
and yes, thanks to Zedmin FX for providing the DynaComp build!

Questions, criticism, whatever, lets hear it.
you may want to do the whole inside of the enclosure with conductive paint and ground all sides just to be sure you have a good Faraday cage ...
... nice work

one step ahead of you, its painted with a highly conductive shielding paint from LessEmf.com ;)
Cornish Hens, Cornish Pixies..... when something is referred to as "Cornish" doesnt that imply that it will be tiny? so what gives? ;) just kidding you, I couldnt resist...
that is an amazing amount of work, very impressive!
Most impressive.
Did you design the power supplies yourself?

Quick question, the 9V jacks in the picture look like they are all daisy chained together. What would be their purpose?
those are 4 DC jacks for external FX. they will share a single 1amp 9v power supply. This will power the Wah mostly, but also any external FX, switching boxes, that I need to add will also be powered from there.
Every single other effect has its own AC transformer secondary and an independent rectified, regulated and filtered power supply to avoid any possibility of ground loops.
I have not updated the pictures, that power scheme is very old. new ones coming soon!
here is the trasnformer all wired up:

Hooo-eee that is some serious iron!
the czech republic does some fine work! 70 bucks!!!! Not too bad really, the quality is unreal!
15 outputs baby :icon_lol:
There needs to be more pictures stat.
I love this project, hard.
Here is my layout for the PSUs...I think its final. Also im making a few tweaks to the 3pdt bypass and the Adjusticator and buffer pbcs.
(http://i23.photobucket.com/albums/b379/sjaltenb/9vpsulayout.jpg)
and here is jack ormans simple buffer/splitter layout I made for the delay splitter. I'm new to layouts so i know its not great but it should work...i had to put a jumper in there off the transistor but oh well...it makes for a decent layout i suppose. i know i could have just used his layout but i wanted to do it myself :-\
(http://i23.photobucket.com/albums/b379/sjaltenb/delaysplit.png)
Learn how to do ground fills in Eagle. It's REALLY easy. You click the "Draw a Polygon" option, set the isolate to something bigger than 0 (I use 20 mils for low power, 30-40 for high power stuff) and draw a box around the edge of your board on the bottom layer (pretty much RIGHT inside of the white lines). The isolate just determines how far away the ground plane is from the traces, so tweak to taste. When you're done, right click on the new polygon you drew and name it "GND", which will connect the polygon to the ground connection in your circuit. When you click the "Ratsnest" button... VIOLA! Instant ground fill.
This could especially save you heartache on that first board, your ground is pretty darn weak. And on the second board, it looks like the spacing between a few components and traces is a bit close. For the electrolytic caps going to the resistors, make sure the trace doesn't come to close to the square pads. For the top-left resistor, raise it up a little bit as it's kind of close to the large pads right below the part. Also, on the fourth resistor from the left, the top part isn't connected to anything. In the window editor, make sure that your wires are actually connecting to the parts. The easiest way to do this is to clock "move" and drag the parts around, all of the wires should move with the parts. You can avoid these problems by using a grid of either .1 or .05 inches (.1 is the good default, .05 is for "finer" work like on a microprocessor).
Thanks Cliff!
yeah I did figure out the ground fills but was hesitant to use it on the PSU because the actual layout didnt seem to need it. However I suppose it would be good to have a good strong ground on it... I will change it and post an update
Thanks for catching those mistakes on the buffer board!! I don't know how i missed that one part :icon_redface:
I'll get there one day...
Cliff already explained everything you need for the groundpour.
Some more details and explanation can be found at gaussmarkov's site:
http://gaussmarkov.net/wordpress/tools/software/eagle/ground-pour/
(http://i23.photobucket.com/albums/b379/sjaltenb/9vpsu.png)
PS...Special thanks to Papa for the original layout design for the PSU. It doesnt look like it there but the traces are .4 and the isolation is .25. i am leaving room for a clip on heat sink, thats why there is so much spacing. I need to check the sizes of the electrolytics too... i'm using nichicon 2200uf@25v, then 100 and 470@16v. the others are .1
(http://i23.photobucket.com/albums/b379/sjaltenb/buffer.png)
Here is the input splitter...same design just without the 4th output. This should be a little better...
It's looking great so far! I would like to build something similar, but I don't want to go thru all the effort. :icon_redface:
I'd use a bit wider isolation on the PSU, something like .30-.40. But if you can etch this : go ahead ;) impressive work mate!
thanks auke, probably a good idea!
one thing i was thinking about doing.... I have a ton of extra male/female molex socket connectors. I was thinking that I could place a male socket on each PSU that taps into the 9v output and ground, this way once the entire board is wired up, I could first Test each effect with a battery (by plugging it into the power supply test socket) to make sure everything is working...then disconnect and use the transformer after all seems to be working. It seems this would be a nice way to isolate power noise issues by determining what happens if I use a battery, without having to unsolder a single thing, i could just cut off the AC mains and plug right in....
Seems like a good idea to me...here it is:
(http://i23.photobucket.com/albums/b379/sjaltenb/9vpsuv5.png)
Also, here is my Adjusticator Layout and schematic. definitely a work in progress. I just left pads to wire the pots in with. I am using it to control line level rack delay levels for the Send/Returns:

The board is almost up and running. I am waiting on a bunch of PCBs from John Lyons (power supplies and 3pdt switching pcbs)
Today I tried to make sure every circuit was ready to be wired up, doing odds and ends, etc. The EQs still need to be mounted, which will be a pain, and some spare parts for a few fx here and there.
I have used about 200ft of belden paired cable :icon_eek:
The transformer, input/output board are all ready to go, as well as amost every effect. It is hard to think about how the entire thing is routed, really gotta take your time and think about it. Heres the latest pics, the coil of wires on top are for the PSUs-FX, and the other large coil to the right is for all the s/rs, volume, wah, whammy, etc.
Some of the FX circuits are kind of just floating there until I solder the wires, then I will secure them to the board. Anyways, enjoy!

Question: I am going to mount the Power supplies on the back wall, to the left of the in/out panel. Do power supplies themselves "radiate noise" like a transformer does? I think if I have any problems I will just encase that entire area with a metal wall....The closest effect is a GE7 and the delay mixer... Every single wire is shielded to ground
impressive work mate! I'm looking forward to the clips and vids of this beasty in action!

Yes, beware of radiated hum from transformers! In the second pic from the bottom, I have mounted a slimline mains transformer under the shelf. I am experiencing hum pickup on any pedal placed directly above, and also stray pickup on 9VDC cables is getting into the 'gainy' pedals and causing hum/buzz.
http://www.steveevans.org/pedals/
I am looking into a small toroid in a metal case under the shelf, or at worst, an EXTERNAL PSU...nooo!!
Well the curiosity was killing me so I had to see for myself if this whole thing was going to work, granted there were a lot of variables that were left out of this mix. Throughout this entire project my #1 fear has been excessive noise. the whole point was to cut down on the noise, not add, So i have taken an overly proactive route in building this thing, to ensure I do all I can from the beginning to keep the noise out.
the vintage Tube Driver is the highest gain pedal that I have that is close to the massive transformer. It runs on 12V ac, directly from the tranny. I'd say its about 6 inches away.
Using my makeshift, unshielded test rig, I connected the signals to the tube driver. I went ahead and wired the mains to my power entry module, screwing the earth into the enclosure,and attaching the tranny shield and the AC lead's shields which all converge to a strip by the transformer.
Now, of course the transformer was far from loaded, so the radiation was probably not near what it will be once all 14 outputs are being used. However...
No noise! . I was getting a healthy 13.2VAC out of the transformer and The TD fired right up and sounded awesome! I cranked the gain and volume and it still noiseless
This was pretty encouraging. Of course, a lot of things will be added and changed by the time I'm done, but hey, its a start! I'm getting so close!
I remember seeing a diagram of your grounding scheme at some point, and I wanted to look at it again, but can't find it. I am building my own multi-effect (set up more like a modular synth than a pedalboard) and I need some ideas on how to ground everything without ground loops.
Can you post that diagram again? Thanks.
Yeah I will see if i can find it. Im on another computer right now.
I just ran some tests with the transformer-->power supply--effect. It seemed to be OK. Not perfect yet. I am still not convinced that my little test rig does not induce ground hum. The power supply is putting out a perfect 9.02V though which is good. The modulation effects are taking to it EXTREMELY well. The high gain stuff is, well, high gain and its going to be the noise producers
The way my grounding runs is thus: Ground in from FX board goes to the ground of the power supply. The power supply has a "ground in" pad which is wired to the star ground. So basically everything eventually hits ground. I just made it convenient because the 9v and ground from run the PSU in a single paired cable to each effect.
The input/output panel has all the sleeves physically connected to the metal plate. The plate then has a single wire running to star. All wire is shielded to ground.
I have the pic you send me in my inbox Stephen. If you want me to, I can post it for you.
Updates!
almost Everything is wired up and ready to go, my switch and power supply PCBs should be here soon:
(http://i23.photobucket.com/albums/b379/sjaltenb/cornish007.jpg)
These will hold two LEDs to shine up on the panel and will soon have a black cover over the bottom 1 3/4" of the panel
(http://i23.photobucket.com/albums/b379/sjaltenb/cornish001.jpg)
more wires.

(http://i23.photobucket.com/albums/b379/sjaltenb/cornish009-1.jpg)
This panel mixes the delays (Delay 1 Repeat volume, delay 2 repeat volume (both are remote rack units) and the 3rd is the parallel mix for the Tube Rotosphere. The switches are Dry Kill (kills the main signal into the mixer) and the 2nd is Serial/Parallel option for the rotosphere
(http://i23.photobucket.com/albums/b379/sjaltenb/cornish008.jpg)
Here are the EQs. All i have to do is glue the faceplate down...
So far its been about 250ft of cable, almost all of it paired, so roughly 550 ft :)
Wow. Keep up the great work! I would cry if I had to do all that off board wiring. :icon_mrgreen:
Wow you are really getting on with your build now! Sorry I havent looked in sooner but dropped off the radar here for a little while.... Thanks for the mention about the Ealge work on the PSU. cant wait to see it finished
More pics!! More Progress.
A HUGE thanks to John Lyons for his help buildling the PCBs. I have now populated all the power supplies, and mounted all the switch PCBs. The switches are 3pdts but switch two LEDs, have ground connections for the LEDs and for grounding the input, power for the LEDs and also provide grounds for all the shielded cable.
I got a lot of the wiring and signal routing done.....but theres always more to do :)

The board is up and running and HO-LY- CRAP its amazing!!! So quiet I dont even believe. The only noise this thing puts out is anything that comes from the guitar. If phase cancel in position 2, I can crank whatever effects I want to the max, Compressor+fuzz+tube driver and nothing, zilch, silence. Until I play a note!
I havent installed the buffers yet, so the tone is a little dull, but So far I am amazed. All the work has payed off. Effects that are up and running:
Skreddy Lunar Module
Colorsound Power Boost
DynaComp
BYOC Muff (triangle) +its GE7
Tube driver 1 and 2
phase 90
microvibe
2nd Ge7 for Distortion
_________________
Still to do:
Fix and install CS2
Wire Master EQ
Add external trimp to CE2 and its done
Build buffers and splitters
wire Delay mixer
wire the electric Mistress
rewire external power jacks (wrong + lug, do'h!)
Add a power supply for the LEDs and Fans
Hum Free amp splitter

Phew! All the power supplies work great, my grounding seems to work great. Theres not TOO much heat but the fans will be for fun.
If you cant tell, the two power board are stacked and very stable. (#8 bolts). Enjoy!

That's.... well, that's pretty dam ridiculous! :icon_eek:
Massive achievement. Really good work.
Make a vid of it in action?
Thanks!
I will once all the fun stuff like the LEDs and fans are all done, along with the rest of the effecst.
On a different note...those fans are NOT just for style points I just figured out! With the back off, and most of the power supplies running and power effects (say around 70% of max...NOT counting the 2nd transformer and PSUs for the fans and LEDs)...the temperature around the back of the board was around 120 degrees F! That transformer was putting out some heat!
So i plugged the fans into a wall wart to see if they helped and voila! A healthy ~82F. I imagine that once all the rest is installed, especially the 2nd transfomer and with the back on, it would have only gotten hotter! Good thing I put them in. Plus they are very quiet, and only cost me $12 bucks.
Which way have you got the fans going? I'd think maybe about making the one on the left in that pic above the "exhaust" and the one on the right "intake" - take the air off that hot transformer and dump it straight outside, rather than blow air past it and end up filling the box with hot air as a result?
Those tubes in the Tube Drivers will also add their fair share of heat? You going to get a pair of mini-fans for them as well, blowing the waste heat towards the exhaust?
The board is now fully functional! Besides the LEDs....waiting on a transformer
Everything is installed and working!!! Sorry for no updates lately, but I'll try to take you through with some photos. Lots of wiring!
For reference, this is how the signal chain ended up (final)
Dual Input w/ Switch-
JFET Buffer/Splitter- Out to tuner
Wah Loop w/ Reverse Switch for "Echoes"
Colorsound PowerBoost Clone
Skreddy Lunar Module Fuzz
Boss CS2 Compressor
DIY DynaComp Clone
Chander/Butler Tube Driver #1
Remote Whammy S/R
DIY RAT w/ GE-7 EQ
Spare Distortion Send/Return- Shares RAT GE-7
BYOC Triange Muff w/ GE7 EQ
Chandler/Butler Tube Driver #2
Electric Mistress w/ LBP2 Boost
BYOC Phase 90
VooDoo Lab MicroVibe
Boss CE-2 Chorus
Boss GE-7 EQ
S/R For Hughes and Kettner Rotosphere with Series/parallel mixing
Volume S/R
4 Way JFET Splitter--->
GGG Mixer Inputs: The digital delays only return the repeats to mix with the original analog signal.
1)Dry Input w/ Defeat switch for checking delays
2)Send Return for TC Electronic D-Two Delay
3)Send Return for 2nd Rack Delay
4)GGG PT-80 delay (onboard) with dry defeat switch
The Dry signal and 3 delays are then sent to a GGG ABY Amp Splitter and Out to amp(s)!
The Board also has 2x 12 Volt fans, blue LED backlighting with dimmer, Red LED indicators with dimmer, 4x250ma isolated external 9VDC outputs, addditional 120v IEC output, and....ZERO NOISE!

:o
That thing is raw!
I'm really impressed. Great work!!
Hey man,
great board. How are you switching the Boss CE-2 on and off?
Thanks for your time.
Martin
Hi,
The CE2 was modded to stay on all the time (no transistor switching) and the in/outs were put in a true bypass loop.
The enclosure is for sale on ebay, and is listed in the for sale/trade section.
Check itt out if you are interested.
If I talked much, I'd be speechless.
