okay I've built 4 byoc pedals, but now i want to start making pedals from schematics, and layout my own circuits and whatnot, but i have no idea where to start. i've gathered a bit of knowledge with the byoc pedals, and i ordered parts to make a green ringer with a schematic i found over at tonepad. ive followed the schematic as best as i could but i cant get the thing to work. can anyone give me some advice or point me in the direction to learn some stuff about pedal circuits, like how the different components work to create the effect and i guess just beginner knowledge of pedal circuits? id really appriciate it.
