The 3PDT-05 is a redesigned version of the 3PRR project on madbeanpedals. It combines two utility circuits into a single PCB: a charge pump/voltage inverter and a bypass switcher. The switching mechanism is true bypass with the effect input grounded. The charge pump section can provide various voltage outputs, including + or – 9v, +18v (unregulated), and/or +15v (or +12v) regulated. These outputs can be used simultaneously, as long as the circuit load does not exceed the current supply available through the charge pump. The current supply ranges from 20mA to 100mA, depending on the charge pump used.
