The Wholly RollerTM Volume/Expression Pedal is quite versatile. While it's a perfect companion for either the Rang III or Rang Chorus*Delay pedals, it can be used with any manufacturers' effects that accept a TRS expression pedal input. The initial version is mono but it can easily be produced as a stereo model if there is demand. The impedance is 300K ohm, Â±10%. The foot print is 6" x 3.5", and it's about 2 1/8" tall.
It's small! It won't take up much precious pedal board space.
Can be a compact volume pedal: volume in / volume out.
Can be a compact expression pedal: 2 jacks to accommodate varying polarities of different effects.
Two through output jacks for connection to a tuner or for other signal routing.
