Pre-Owned Electro-Harmonix Mono Synth

***This is a pre-owned item in very good condition with velcro on the bottom

From "Superstition" synth bass to "Blue Orchid" stacked leads and beyond, the EHX Mono Synth infuses your guitar signal with 11 vintage monophonic synth emulations straight out of the '70s and '80s. No instrument mods, MIDI, or special pickups are required — just plug straight in as you would any other pedal. Once you dial in a sound you love, save patches to any of 11 user presets and recall with lightning speed. The Mono Synth's Dry and Synth knobs let you blend back in a jigger or snifter of your untouched guitar signal for note clarity and enhanced realism. An expression pedal input (pedal not included) unlocks real-time parameter control without touching a knob.

Plenty of room for extra tweakability

There are so many cool sounds that you can dial in with EHX’s Mono Synth pedal. You get 11 great-sounding synthesizers to start from. The Sensitivity control adjusts how your playing dynamics trigger the synthesizer, allowing you to fine-tune the pedal’s response to your rig and playing style. From there, you can adjust a key parameter for each of the 11 synth types with the Control knob. And — if you’re still hungering for more — you can use the Mono Synth’s Expression input to gain real-time control over an entirely different parameter. Beyond that, you can create, save, and recall 11 user presets, one for each of the 11 synth sounds. At Sweetwater, we appreciate the Mono Synth’s inspiring combination of intuitive operation and profound tweakability.
