Cool,where did you find these? Thanks for your interest in this project. I must have done something wrong in my wiring. I still can't get it right. It did work when I first plugged it in though.

Hope its OK to resurrect this thread. I installed the psycho knob in my amp and yes it does suck a battery dry pretty quickly when its shared with the power amp. Especially on the highest setting which gives me a nice lo-fi fuzz effect, albeit noisy. Works better with an external power supply bit still noisy.
Just wondering if I use separate batteries, will the power amp still work in bypass mode if the psycho battery is dead?

Also does anyone know the max voltage for the psycho knob? Artec website says it can work down to 5V but no max is given. My amp can use 8-18V.

I lost the paper that came with mine while moving, but I believe the operating voltage is 9V to 12V.

Use 2 9volt batteries in parallel for longer use or a 9volt Walwart with a high milliamp rating(800ma or higher). Walwarts can sometimes cause RF noise in your amp though.
