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.

Run Off Groove Phozer V1

I came across the schematic for this while looking through RunOffGroove.com. It's an interesting mashup of Tim Escobedo's Idiot Wah and the LFO section from the EA Tremolo to produce a faux phaser effect, and apparently works very well at higher speeds.

    2. Just went back over the layout and it should work. The only thing my layout doesn't include from the schem is the LED for rate indication. That would go between the 10k from the voltage rail to the collector of Q4 if anyone wants to add it.

  2. Hi! In the schematic there's no diode from 9v (1N5817). What is its purpose? It should work without it, right? Greetings from Argentina

    1. That diode is for polarity protection. You can replace it with a jumper of you don't want that feature.

  4. I built this and i put a 1M pot in place of 1.5M wired on the Depth 3 and works. I used the vero layout from Parasit Studio. But mine sounds more like a tremolo.
