These are a few of the other projects and pedals that I have built for people.
This is a mixer and buffer pedal. It has a two channel mixer and a separate high impedance buffer that can be selected to give 0dB or +6dB boost.
This is a high functionality ABY switch pedal that has adjustable buffers on each channel with a -6dB to +6dB range, a phase reversal switch on the B channel and transformer coupled outputs on both channels.
This is a VU meter and mute pedal that can be placed on the end of a pedal chain to assist in setting up of volume levels at live events.
This is my version of the Big Muff Pi Green Russian.
It has two enhancements. One is a switch to select alternative clipping diodes. The other is an extra tone shift control to provide a flatter frequency response curve.
