Multicab SIM..my own design cabinet simulator .. it works!! cool!

[domdec314]

Awesome stuff. Anybody ever find the bass version that disappeared?

+1

I'm also highly interested in the bass version.

Hi,
I just breadboarded the circuit (without the stereo stuff), it actually sounds great ! Thanx a lot for that nice project, Daniel !
Best regards.
Eric

any sound clips?

[J0K3RX]

Zombie - This is an old one but from the sound clip on the first post from dschwartz it's a great sounding sim!

Here's the sound clip if you missed it -> http://www.goear.com/listen.php?v=bec1880

I used the "Compare to Schematic" verification tool and passed 100%

nice, thats got a good range to it...

Jim are your boards available for use at a PCB service?
I notice that one is double sided,too much for a toner transfer etching.

If so can you post a link?
You have a few other PCB's I would like to try when I am able to afford too.

Bryan, I was gonna do a run of them but haven't had the money or the time lately... I uploaded the gerbers to OSH Park and shared the project so, if anybody wants to have a go it's about $22.00 for 3 boards.. a little over $7 per board, all ya gotta do is order them..

I reorganized the original schematic, you can check it here. If you order them you will have to use this schematics RefDes to populate the board.

Other than the part designations being redone, it's identical to the original.

Here is the board check against the schematic with 100% no errors. So, if the schematic is correct then, so is the layout...

Here is the front and back of what you will get..

Thank you Jim,
Thats not a bad deal if 3 people were to get together it would be about 9$ a piece after shipping twice.

I was hoping your tube pedals and fet emulators would be on your OSH profile,I was thinking I would just order one of each as it would cost about the same as etching after buying the stuff to make more ferric chloride and some copper clad,drill bits,acetone, granted I could make about twice as many etching them myself,but for the time and trouble involved using good quality PCBs that are already pre fabbed and drilled,ect saves a huge amount of time per build.

Now that I think about it,after including toner ,and everything involved,getting pre made PCBs VS etching yourself I think the only advantage to etching your own is the satisfaction of doing it all,and the ability to make a quick test PCB with out waiting for turn around and having enough designs to warrant placing an order.

^ yeah i'm with you there, ive been getting my head around eagle and the upload procedures....slowly.. 

its a bit of a  faff at first and am still learrning , but the end results are worth it imo...i'm waiting on some chasm reverb boards. (seeed not osh)

[deadastronaut]

finally breaded this up.....very cool..

ive been on a cab sim quest lately..

[Renegadrian]

A lot of images of these past posts are gone, including all veros but one - can someone upload them again!? final schem is the one at the first post!?

[deadastronaut]

hi adriano, i breaded the first page schemo IIRC...

[Hatredman]

+1 here.

I'd love to try this one, but all schemos of the thread are gone!

[Hatredman]

Oh, my...

I spent yesterday and this morning retracing the circuit based on alexirae's vero layout, because all schemos were gone, and now when I was ready to repost it here Jim's files are back online. Maybe it was a glitch on Dropbox.

Jim's files:
- PCBs at OSH Park: http://oshpark.com/profiles/J0K3RX
- Schematic: https://dl.dropboxusercontent.com/u/11178619/Cab%20Simulation/Multi-cab.pdf

I loved the fact that Daniel used two capacitor multipliers ("inverted gyrators") for two of the filters.

FYI... I happened upon this the other day and seems our long lost friend Mr.Noisemaker has indeed been making some Noise!
\m/ \m/  And a pretty damn cool cab simulator + DI box as well http://www.dsmnoisemaker.com/

I like it! Double Trouble +

Hey nice that you noticed!!

I took the multicab sim idea a few steps further and it turned out pretty nice!!

Yeah man, I like it a lot and you did take it few steps further! Really great sound, very versatile and if you are trying to sell a lot of these it was a great break getting Ryan Bruce to demo it on Riffs, Beards & Gear!! I watch his videos all the time to keep an eye on new stuff and he is a heavy player which I dig... 

[dschwartz]

Yeah i have mixed feelings about that video, fluff spoke wonders about it, but the sound track was not good..he set it up too dark and buried under the mix...it really sounds much better than that

Yeah.. does sound a bit buried and dull in that demo. You could ask him to re-mix the video and bring the guitar to the front a bit more? On the other hand it looked like he was using the "Two Notes Le Lead" for the preamp which I have yet to hear a good demo for... Ironically, this video for your OmniCabSim is the best sounding demo for that Two Notes preamp that I have heard so far. I think maybe if he would have used a different preamp like the MXR EVH5150 pedal or the Atomic Amplifire it may have sounded a little better but I dunno..  He seems to be more of a straight up amp/mic/cab kinda guy and has a bit of trouble getting "that sound" out of simulation pedals etc.. I think he tries to dial it up in the DAW where he usually does for real amp/cab/mic setups and it doesn't pan out the same. Anyway, I know the feeling of having somebody demo your stuff and then being like WTF, that sounded like total sh!t! You don't want to ask them to try it differently or run it a different way etc cause they are basically kinda doing you a favor anyway...

You could send one to Ola Englund for a demo  At least you know it would sound exactly the same as all of his other demos that all sound the same...

[dschwartz]

Yea ..i rather make more demos myself or find other guys, i ran out of units to give away..maybe when i make a bigger run..but i have to redesign the pcb to fit more options and match the enclosure..its a pita..

[JCSIFU]

I'm confused, where are the other two pots on the layout?  The video shows 6.
