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.

Seppuku Octave Drone

Here's the Octave Drone from Seppuku FX. Like the Space Fuzz, it too is based on the Rambler. In fact, the Octave Drone is more than half of the Space Fuzz. This has as input switch that goes between a 4.7nf cap and a 100nf cap, much like like the Hot Silicon Tonebender. You could easily replace the switch with a B100k pot (much like the Basic Audio Scarab Deluxe), to pan between the 2 caps. You can mount the pots on the component side to have the board mounted vertically inside your enclosure if you so choose. Should fit in a 1590B without issue.

  3. I built it like you suggested with the switch changed to a potmeter. Works like a dream. It's a nasty little fella.
    It picks up the octave better with my guitars than the rambler or the tentacle.

  4. Works like a charm! Tried 4148, LEDs, 34a and 5817, the last two were the best.
    Keep'em coming bro.
    Greetings!
