Recent build of Low Tide Modulator (Shallow Water clone). Using a J201 instead of the SK208-Y. Also a MN3207 instead of the VD3207D BB chip. When circuit is on, signal goes through without issues. But no effect is heard at all. When Mix is all the way up, no signal is heard. I played around...

Solved. Maybe some bad traces, but I ended up having to ghetto this thing like in the included picture. Using my mm for continuity solved the problem quickly.

Nope, I have it coming out of the Switch and it dies at R17.

Here’s the part of the schematic

You’re right, I swaped the mini board for a proper one. Signal enters boost circuit and dies right away. Doesn’t even reach C10.

Finisned putting this one together. OD side works perfectly, but boost not so much. When I turn it on and dime the boost knob, sound starts to stutter frantically. And it doesn’t boost, it just just muffles the sound. Also, with my audio probe, this is the weirdest thing I’ve seen : I clip my...

Pumbaa Distortion issues Hey gang, having weird issues with this pedalpcb Pumbaa Distortion, aka Thorpy Warthog. The volume knob and Calibre knob work as they should. But the Gain knob barely makes an audible difference, and there isn’t practically any gain audibly. And the tone does nothing at...

Do you think that it would cause the breaking up in the sound?

Bi phase distorts when digging in to strings This recent build of mine works perfectly except for the slight unpleasant distortion sound when i dig in a little on the strings. What could be causing this?

Its now fixed, it pulses correctly now. Except that I get a lot farting distortion if I dig in a little on the strings. Oh, and the spdt switch cuts the signal in one of its posistion. (I double checked, its a On-On)

Right after posting, I noticed I had put a 47p cap instead of a 47R resistor… duh!

Hey all. When headers soldered in, bypass works and led lights up, but no sound when turned on. The 7371 bulb however just stays lit, never pulses. And it only lights up when the gain trimpot is turned up all the way. Any idea what could be going on?

Yes, they are in fact negative. Typo on my part.🙃

Hey y’all! I would really appreciate a new set of eyes for this issue. My Muzzle noise gate has no sound when on. Bypass works. Getting proper 9v entering the pcb. Here are the voltages for TL072 : 1-nothin 2-nada 3-1.2mv 4–8.36v 5-1.7v 6-nada 7-nada 8-8.72v And the LT1054 : 1-8.72 2-4.37...

Building a combo with a Tyrian distortion (Revv G3 and a Muzzle(zuul). My Tyrian kicks ass, but I get no sound on the Muzzle. The led works. Bypass works. Getting proper 9v entering pcb. You guys see anything I’m not? Here are the voltages for TL072 : 1-nothin 2-nada 3-1.2mv 4– -8.36v 5-1.7v...

Here are some pics

Currently building a Propolis fuzz. Worked great before putting in enclosure, now the fuzz circuit is very week, very little fuzz coming thru. If I press on the resistors (finger in front and thumb in the back of pcb) the fuzz comes back. Any ideas?
