I have this EP/OCD combo from Mas Effects (https://shop.mas-effects.com/collections/diy/products/ocd-ep-booster-pcb), have one small issue on the board that I've narrowed down to a section of the circuit right around the op amp but I'm wondering about the footswitch wiring. See the attached...

Hey, having some trouble with this one and hoping a fresh pair of eyes will help clear them up. Build doc here, schem on page 2: https://4f3d79f5-cd8b-4c1f-8c04-cc8a4c753d0a.filesusr.com/ugd/ff4c6c_4679daada1c24ebd88904170cb24fc95.pdf I got it wired up a week ago, and was getting sound but very...

I didn't know the hammered copper enclosures could take a print job, that's neat.

I like using these to add a boost pot to another build: https://oshpark.com/shared_projects/nsJTeQK0. They're tiny and easy, but FYI they are LOUD.

I completely forgot about this thread. Thanks for reminding to try biasing this thing once again.

Thanks all. Was debating between the switching diodes and an EQ circuit in there. May just have to do another with the EQ using whichever diodes I like the best in this one.

I have a functional pedalpcb DOD250 without the diodes, and I'm trying to wire this (https://drive.google.com/file/d/1YSbrA-hZEN5xtWxdzNkJDVAUvD-Z9BPc/view) into the circuit. I can't see the traces on the 250 board, and the silkscreen just lists the suggested 1n270 diode, so I'm having a hard...

I grounded the led at the 3pdt, attached the anode to 9v, and it's all good. everything works. not sure how i got that mixed up.

Wait, is pin 4 just a ground for the kathode, and I've got it backwards? If so, where would I hook up the positive lead so that it only turns on with the switch?

This is a Breakfast Audio Big Nothing (squarewave distortion) with a SHO in front of it. Pics attached, I cannot get the LED on the right to work. I've tested it and it lights up in diode test mode with the DMM. Anode is wired to pin 4 on the 3pdt, i've attached the kathode to the center pin and...

I'm not sure how to delete a post, but turns out I had a bad solder joint somewhere in there, probably on c1. Reflowed with a really hot iron, and it works great now.

Working on this double boost pedal from Mask Audio, the Electra/clean side is working fine, nice and loud. The Speaker Cranker side is really quiet, and I noticed that the volume is maxed at full ccw. Seems strange to me, the doc says that pot should be a B5k but I've used C5k when doing SC on...

This one is driving me crazy. Pics attached, I ripped off a few solder pads and traces in spots, but I'm pretty confident I repaired them and got them connected (see D3 to Q3 for example). Plugging in the pedal, I get the sound of a naked cable touching metal, loud low buzzing so I want to say I...

Not sure how I missed that. Ordering today, thanks!

I'm slowly putting together a Glenn boost from Dead End fx, and it requires a BS250 at Q7. Build doc here: https://drive.google.com/file/d/13ONBUsW9pupaBKN3IMsFB7r3JdT9Ruli/view Having a hard time finding these at a reasonable price, Mouser is backordered. Is there a more widely available...

Actually I just realized the Kliche breakout board doesn't have a specific LED pad, it's S1-S6. Any idea which of those corresponds to the LED?

Thanks!

I found an old Kliche, one of my first builds, when I was scavenging for spare parts, and decided I should reassemble it. Only problem is, when I was first working on it, I ripped off the solder pads for the LED. How would I go about wiring up the LED without these pads, should I just go CLR -->...

as far as i can tell, it worked fine before and turns the effect on and off. Really strange.

it's bothering me the the led suddenly isn't working. There's nothing about replacing those ICs that could have affected that, right? Problem has to be that I messed something else up while doing it? I get 8-9v at the protection diode and on the anode led leg. I've never had to troubleshoot a...
