Charge Pump Switch Board

3PDT switch mounted charge pump PCB for positive ground effects. This small PCB simplifies the wiring of 3PDT foot switches in guitar pedals while also offering -9V when used with a standard +9V power supply. This is a great option for positive ground effects such as vintage fuzz pedals. The circuit of this PCB also features a protection diode and an LED indicator for when the effect is engaged.

This board is compatible with the MAX1044, TC1044S, TC7660S, and LT1054 charge pump ICs.
