DR Boogey build report with pics and clips

[bancika]

Hi folks,

I finally finished this pedal many months after I got the PCB from John Lyons. It turned out AWESOME! Thanks to anyone who contributed to this circuit and layout.

Couple of pics








Few notes:

• Instead of decals I put a transparent laser engraved plexi scratchplate. It's attached to the enclosure with thin stripes of double sided tape on both sides.
• All fets are J201 and biased close to 4.5V
• I used 47uF filter caps because I had them around and 2K mid pot.
• I used #20 teflon wire which is a b*tch to work with in tight space.

Update:

I just tried it with my Ibanez RG Prestige and it may have too, too much gain. With hot-rodder strat style guitar I played for the last two days it's manageable, but with ibby it gets very distorted very fast.
Couple of quick clips with Ibanez -> Boogey -> (Boss DD-20 delay on the second clip) -> Boss Micro-Recorder, only cab sim is ON

It sounds better through real amp, I'll try to record something with that setup.

Congratulations, I really like your work with this pedal.

Good job on the build, nice sound bytes!  Sounds good!

[bancika]

thanks guys. I'll probably have to play with some lower gain fets the next weekend. With my hot strat usable gain range goes to 50%, but with ibanez not more than 45% Too much gain

[Ibanezfoo]

I have the same experience with my Dr. Boogie build.  Anything over 50% is just about too saturated.  It still sounds really nice up until that point though so I'm not complaining.  My 5150 head is the same way though.  Anything past 6-7 on the lead pre-gain is just super saturated and loses the crunch.

[ayayay!]

I really like the topside of your Boogey!  Great job!  But I gotta ask, why did you goop up all that solder on all of the traces, everywhere?  Was the etch that unreliable? 

[bancika]

no really, etch was done by John Lyons and he did a great job. It's just that I noticed that traces started corroding and couldn't find my board protection spray. My iron tip isn't that good for tinning surfaces so it ended up looking a bit ugly. But it should last forever

[ayayay!]

board protection spray

See, right there.  You learn something new every day!  I didn't know one needed such a thing. 

[bancika]

yeah, and I was given a great spray that you can apply to the whole board without masking solder pads. You could even solder through it...

nice work bancika!! beautiful finish, very classy!!
question: why the sockets for resistors?

[bancika]

thanks
sockets are there to be able to play with bias. I put the pot in, tune it and replace with the resistor. In case I want to try another FET (which I do) it's easy to swap both resistor and FET with sockets.

damn that´s a great idea!

Wow talk about timing.  I just happened upon a load of resistor & capacitor sockets!  Would you guys be interested in them if I posted them in the FS forum?  

They basically look exactly like the 3 hole sockets in the pics above, but the center hole is missing the pin.  They're EXCELLENT for prototyping & quick mods, especially for caps!  I've always been frustrated doing the "one-tiny-socket-at-a-time" thing like bancika did above, and forget trying to pull that middle pin out when there's 3 sockets.  

I'll post pics tonight.  What do you think?  

P.S. sorry to steal the thread.   

[bancika]

here's another clip, this time with some wah (dunlop q95)

ayayay: that's cool, probably better than individual pins. These look like they're gonna break if I'm not gentle with them...

[Brymus]

That sounds as SWEET as it looks.
Excellent in both areas.
I am gonna have to try one of these pedals now as well,thanx to the sound clips.

[bancika]

tnx 

[EARNEST]

what kind of a board protection spray we are talking about? to protect the PCB or enclosure? :-/
P.S. ok...most probably, it's for the PCB. what brands are good for this kind of a job?

[bancika]

it's PCB protection spray and I just found it in my father's workshop
This is some yugoslavian brand that I doubt you can find...don't know any "western world" brand..

Cheers
