The Blender Parallel Signal Mixer utilises an OpAmp driven circuit that allows the user to blend two separate pedal chains in parallel. It has two independent channels as well as a full bypass mode. Additionally there is also a phase polarity switch on the first channel loop that can enable functionality with inverted phase pedals - this also produces interesting results on non inverted pedals too! To add the fun I have also added the ability to control the blend via an expression pedal.
I recommend also picking up the Johnny Five 3PDT footswitch to compliment this project and provide the LED power indicator function.
