The Sultan v1.1

Heres an update to the Sultan. Read about my error in the first version of the pcb here. I made a mistake and the jacks grounds were not grounded on the first version. I ordered an updated board from PCBWay.com…

Mother Fuzz

This is Mic Testers Big Muff Plus. It’s a Big Muff with a JFET input and output stage, and a James control in place of the BMP tone control. The JFET input creates a higher input impedance the on the…

Harmonic Energizer

Here is a clone of the Systech Harmonic Energizer. This is a parametric EQ. It’s like a single-band equalizer with a control to set the width of the frequency band that it affects. It also has a control to sweep…
