This is a library of perfboard and single-sided PCB effect layouts for guitar and bass. I'm not an electrical engineer by any stretch of the imagination, just a DIY'er who likes drawing layouts. It is meant for the hobbyist (so commercial use of any of these layout is not allowed without permission) and as a way to give back to the online DIY community.

Switchback Delay

Continuing with the board-mounted (almost) everything theme, here's what I call the Switchback Delay. It's my take on the Deep Blue Delay with a few modifications. More info in the build doc linked below.

    1. Not without cutting traces and butchering up the board a bit.

  4. Sorry to dig this out but I just built it and ran into issues, maybe someone can be of assistance.
    I have no sound. I checked the op amp and when nothing is connected to the input then voltages appear correct on the first stage but when I connect the guitar then the input pin stays at around 2.7v and output pin stays at around 7.3v.
    Can someone guide me in the right direction here? Vref seem as it should be.
    Thank you in advance. This is my first proper pedal build (apart from less than perfect "improvised" fuzz-face thing)
