Skippy Tremolo

This is Moosapotamus' take on the Vox Repeat Percussion tremolo. The Skippy keeps the character of the original, but with more control while covering a much wider range of tones. There's also the option to use the modern 2N6027 instead of the vintage 2N2646. And you can plug in an expression pedal to control the speed of the effect. I've changed the tone switch to a pot for more fine tuning. More info here.

Moosapotamus 360 Fuzz

Here's a bass fuzz designed by Charlie Barth from Moosapotamus.net based on the fuzz section of the classic Acoustic 360 bass preamp. It uses a mix of silicon and germanium transistors. I've made the layout to reflect the combination of transistors specified in Charlie's schematic, but socket and experiment. This layout should fit in a 1590B, but if you want to use a larger enclosure, there's a PCB of this effect for sale here with board-mounted pots.
