Wounded Paw Dual Effects Loop Blender in Expression Pedal shell

Blend between two effects loop using the foot treadle of an expression pedal shell. Toe position is 100% effects loop A and heel position is 100% effects loop B, in the middle of the foot treadle's travel is 50% effects loop A / 50% effects loop B. Either effects loop will default to a clean channel if nothing is plugged into it to allow for blending one effects loop with clean for a wet/dry blender. Phase reversal switch on effect loop A to allow for matching the phase of different effects pedals' outputs.
The true bypass switch is now a soft-touch momentary switch using an audio relay and is activated by pushing down at the toe down position.
On the sides there is a knob for the output volume of the blended signal
Use a standard 9-12V adapter with tip negative jack.
