Update 3/22/15: I was trying to build this one to verify it and realized I'd forgotten the feedback resistor that goes from the base of Q2 to the emitter of Q3. The layout above is updated and should be fine now.
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.

1590A Tone Bender Mk.II
Here's the mighty SolaSound Tone Bender Mk.II shrunk down to fit in a 1590a. I laid it out for NPN transistor, as I really wouldn't want to try and squeeze a charge pump in a 1590a along side the effect board. Like the larger layout I posted last year, you could build the Marshall SupaFuzz with this layout as well. See that post for info on the value changes.
