Expression roller
The exp expression roller works like any other expression pedal but comes with two completely independent outputs. The roller is attached to a dual linear 10k pot that’s compatible with any TRS expression input. You can also change the polarity of either output by flipping an internal switch.
The body of exp is identical in size and build to classic Chase Bliss pedals, making it the perfect companion to your existing gear.
