Wounded Paw Effects Loop Blender in expression shell

Blend your effects with the clean instrument signal using a wah type foot treadle to control the blend. Same circuitry as the Blender V1 but in an expression pedal shell. The foot treadle controls the blend in that 50/50 effects/clean is right in the middle, in the toe down position it's all effects and in the heel down position it's all clean. We can also switch it so that heel down is all effects and toe down is all clean.
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 and a toggle switch to flip the phase of the return of the effects loop.

True Bypass

Use a standard 9 to 18 Volt DC adapter with tip negative jack or a single 9V battery.
