I just completed a Proco Rat on breadboard and upon testing it, it sounds fine until the gain knob is turned up about halfway. At half gain a high frequency oscillation is introduced that gets worse the higher the gain. I assembled it using the schematic from electrosmash.com and used all the same v...

Alright awesome, thanks for helping me out with understanding schematics!

Alright so to put all of it together you would connect all of the +1/2v areas together? I've made this pedal already actually but only followed the instructions on their website which doesn't use the schematic at all and just tells you how to put it together... The whole circuit is on one pcb so why...

So I've built a few pedals and understand how to read most schematics but I've got a couple questions for some that I have seen. Here's a schematic of a byoc British blues overdrive that has an example of both my questions https://img201.imageshack.us/img201/8382/imageydzb.jpg First off is what do t...
