There is a Custom Cable Interface for all of the IN's and OUT's to and from the pedalboard.

The Wireless IN is normalized to the GUITAR OUT until a Guitar Cable is inserted into the WIRE input... at that point, the Wireless receiver is disconnected and the Cable feeds the Tuner/ Wah.





The Roland© GA-FC Foot-Controller is modified with a 1/4" jack to allow connection of an external footswitch to turn on the Boost and Delay blocks simultaneously.





The Power Supply is custom built with three internal switching regulators feeding three 9VDC outputs. The unit has a standard IEC power inlet and is switched and fused.
