TECHNICAL DETAILS / COMPONENTS

The PCB is designed to be mounted in a Hammond′s 1509N1 BOX, as you can see in the pictures. The components to be mounted are of the SMD type to achieve a smaller PCB size. The 3PDT footswitch is integrated into the card to facilitate wiring. It is possible to connect the pedal to an external transformer or a battery. Consult the schematic to see the connections. Only the external feeder option has been enabled in the wiring image.

Input voltage: +9v dc.
