In the words of Old Blood Noise Endeavors:

Pardner, which at its core, is a synthy sounding fuzz pedal.The Pardner also has an effects loop, called Lasso, that has it’s own optional overdrive or allows you to easily partner any other pedal in series or parallel with the fuzz side of the pedal.Its an exploration of sound, how thick or weird can you make it kind of pedal.
