Endorphin.es Plus 3 | Expression Pedal with Integrated Dual Footswitches

Q: Does the Plus 3 require a power supply or batteries to work?
A: No, not at all. The Endorphin.es Plus 3 operates on a completely passive analog circuit. It draws zero electrical power from your setup, meaning you do not need an AC wall adapter, power brick, or 9V battery to use either the expression treadle or the side footswitches.

Q: Will the expression pedal work with synthesizers and pedals from brands other than Endorphin.es?
A: Yes! The Plus 3 is equipped with dedicated hardware polarity switches on the side panel. Because different manufacturers (such as Boss, Moog, Roland, and Line 6) use different internal wiring standards for expression jacks, flipping the polarity switch allows the Plus 3 to match any brand's expression input curve seamlessly.

Q: What can I use the two side buttons for during a performance?
A: The side buttons act as independent momentary footswitches. You can patch them into any hardware jack that accepts standard sustain or control switches. Common live uses include tapping in delay tempo, sustaining synthesizer notes, triggering drum machine fills, switching memory banks, or engaging freeze/reverb tail hold functions on digital multi-effects units.
