So this will be a quick one. These are a couple of utility pedals that a past customer had asked me for. He was looking for a signal buffer and an A / B switch. He needed the A / B switch to switch between the volume and wah out put of his expression pedal. He wanted a buffer because...well he needed a buffer in he circuit. That is all. Well here they are there is no demo video only because...its kind of pointless. I acid etched the enclosures. Thanks for reading.
