Buddy of mine asked me to build him an UberDrive with more low end retention - what's the best way to do this? Looking at the schematic, a few options stick out, increasing C1 or C2, decreasing C3, decreasing C4, increasing R9/decreasing C5? I know removing C6 is popular though unless I'm dumb...

Anyone know of another build that uses this layout, or has anyone created a drill template for this? Doesn't seem to have been posted in the drill templates thread yet (that I can see at least)

Any chance we can get a schematic for The Sproing Deluxe? I have no power to my 4558 and therefore no LFO at all. Hoping to get the schematic with the correct component numbers (the Moonshot is the schematic but with different component numbers it makes it much harder to chase down the issue)...

What voltage are we looking for in terms of biasing the MOSFETs on the Octanaut?

About to build five of these, hoping to order the enclosures pre-drilled. Thanks!

Trying to get through the massive stack of unfinished PCBs I have, the lycan build doc still isn't up but there is a BOM. Unfortunately, what's printed on the board (looks like 11k, there is no 11k in the BOM posted in the missing docs thread) doesn't really make sense lol. The picture on the...

A friend requested essentially a Blink 182 pedal - a Marshall in a box and Mesa in a box with a blend knob to blend the two. I've built both of these individually a few times and figured they should do the job, am I good to just split the input to both effect inputs and then send the outputs to...

I built an ocelot for a buddy several months ago, and all of a sudden about a week ago he complained that it was doing weird things. I met up with him today, and it's definitely distorting when hit hard (he's playing a bass with pretty hot active pups). I tested it on a few guitars and my...

This is less of a troubleshooting question than one I'm asking to prevent needing to troubleshoot later - for the key input on the Muzzle (not the pass through setup, just the single input that you would run from a splitter/tuner etc), the "switched tip" is the contact that gets broken when a...

I just built a friend a Dark Rift Delay. I tested it extensively with both a strat and SG, no issues whatsoever (he tested it at my house with the SG too, so he knows it works properly). He took it home, and if he uses the neck pickup on either his PRS or LTD, the repeats distort quite badly...

I cannot for the life of me figure out why, but I built a Tonevendor MKII and have no effect signal (using PedalPCB test rig). I have signal in bypass, LED power, and voltages on all transistors appear to be correct. Is there any reason the test rig doesn't work when using charge pumps to switch...

Made the mistake of building a Duocast board without reading the build docs, most of the electrolytic caps I used are only rated at 25V. I've built a ton of pedals, but typically they don't go over 18V so I've actually never run into this issue - how sketchy is it to leave the 25V caps? If I'm...

Anyone know what color the clipping LEDs in the Acetylene are? I'm assuming red, but wanna make sure. Thanks!

Would anyone care to explain what the trimpot in the Roboto actually does? That Op Amp is set up in a pretty strange configuration (I'm fairly new to electronics, but it's not the way that I've seen either traditional inverting or non-inverting Op Amps set up) and it doesn't appear to be acting...

I bought two organ donor boards (really wishing the FV1s had been in stock when I bought them right about now) and can't get any wet signal out of them. Audio probe gives signal on pins 1/2 of the FV1 on both boards, nothing at pins 27/28 on either. I've tried reflowing both ICs, didn't seem to...

I know the OG TC Preamp could run up to 32V, and, based on the Pedalpcb build doc requiring 35V electrolytic caps so can the Integral, my question is, does that mean that it can take 9/18V input? Looking at the schematic that's my assumption, I just want to make sure the charge pump can handle...

Anyone know where to find them? I LOATHE wiring pots to the board instead of using PCB mount lol, hoping to find a board mount one

I was wondering if anyone had a schematic for this yet, I got a request to turn one into a bass sub octave, didn't feel like tracing it to figure out which caps to change. Even better, has anyone successfully modded one for bass and want to just tell me which caps they switched and to what...

I accidentally soldered the footswitches to the wrong side of the board, does anyone know the connectivity on the board itself? Essentially, can I just leave it, or will the footswitches control the wrong sides of the effect and have channel 2 run into channel 1? It's kind of deceptive, the...

Built the Circulator board and tested it in the new Auditiorium platform (that thing is very helpful, highly recommend it lol), and I get no phase effect out. Signal comes out clear with the pedal on, so I'm assuming it has to be something with the LFO. I even took the LFO out of the circuit to...
