Guitar Build

For some reason I thought it would be fun to build a guitar, from scratch. And, after a lot of self reflection and deep introspection, I’ve come to the conclusion that it is! Of course I have had to rationalize…

CGS 29 Wave Multiplier Panel

Some years ago I bought some PCB for various synthesizer modules. I thought I would design some panels and build a few new modules. This is a first draft of a panel for Ken Stone’s Wave Multiplier CGS29. I have…

Millenium Bypass – Working!

Millenium problesm all solved with the help of R.G. Who kindly pointed out that I probably didn’t have a path to ground on the out put of the effect. Which was exactly right. After having the Millennium work so well…

Dual Booster now with LEDs!

This has two booster in series in side. First is a NPN Range Master followed by a Sparkle Boost. The idea was Joe Gore’s. The two booster work well together. They each have their own flavor, and together get a…

Box of MOSFET

Rock Box! I was talking to a friend about distortion boxes and the Box of Rock came up. Which got me thinking, I’d never heard one before, and Z Vex always makes good stuff. I found a schematic in the…

Meatsphere?

The Meatsphere I hate that name. Then again it’s a play on the name Meatball. The Meatball, if you are not familiar, is an envelope filter based on the Mutron III. The Meatball was made by Lovetone who went out…

Ugly face with tone control

The Ugly Face has an interesting set of options. The Threshold knob has to be the most interesting though least useful. Last year I thought I’d add a tone control in it’s place. I wanted to build an Ugly Face…
