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.

Montarbo Sinfhoton

Here's a unique fuzz box from Italy for #fuzzfriday. Long, warm sustain like a Big Muff, but with better articulation when strumming chords. There seems to be a couple different ways to build this (circuit is the same, just a few components vary), and it's ripe for modification. Using high gain silicon transistors like MPSA18 or 2N5089s and playing with the value of the resistors going to the collectors from the voltage rail is a good place to start. Check out the FSB thread on this effect for more info. Diodes weren't listed in the schematics I saw, but 1N4148s should do the trick.
