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.

 Just stumbled across this on FSB. It's a tap tempo + modulation add on for PT2399 delays designed by Electric Canary. It is digital so you'll either need to buy a pre-programed chipset or burn the code onto the chips yourself. Lots of off board wiring with this, but it's probably worth if you have a favorite PT2399 delay you want to take to the next level. Check out their site for more info, schematic and the code.


  1. Wow.... this is really big
    thanks alot for this.
    The IC wont be that easy to find around here I will have to go 30km away to find out
    but with this layout Can it produce IMMERSE Sounds (Electric canary)

  2. Thanks for the layout, saved me a lot of time.


  3. Can it just be connected directly on the pin 6?
