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.

Square Wave Oscillator

Came across this Instructable the other day and thought it would be a good addition to the library. Would be a good first step into the synth world and apparently plays nice with guitar pedals. Already built it myself and it works great, and fits nicely in a 1590G.

    1. There isn't one. It generates a tone that can be adjusted. Watch the video

  2. OK thanks.
    a suggestion, for layout.

  3. Be good to use as a tone generator for pedal testing/debugging with an audio probe.

    1. Absolutely. Half the reason I already built it! :D

  4. Is there any way to make the frequency higher? Like tinnitus high?

  5. Wich folder of the library library contains the PDF?
