The Electro-Harmonix Mono Synth Guitar Synthesizer is a monophonic synth pedal for electric guitars. With this stompbox, you can trigger the sound of all sorts of classic, vintage, and modern synths with your guitar, doing so without the use of special pickups or MIDI information. The pedal is meant for monophonic use, meaning it will only track one note at a time from your guitar. This makes it suitable for lead parts and synth-bass lines.

Eleven different effect types are available via the effects Type knob. You can create a preset for every effect type and save it to the pedal with the Preset footswitch, or you can fly by the seat of your pants in manual mode.

The controls are relatively straightforward: Dry and Synth Volume knobs control the output level of the dry and processed signals respectively, while the Sensitivity knob dictates how loud you have to play before the effect takes hold on your playing. The function of the Control knob will change depending on the effect type you've selected.

A 1/4" instrument input is provided, as is a 1/4" TRS expression jack for compatible expression pedals. If you opt to use an expression pedal, you'll find that the parameter it controls will change depending on the effects type you select. The output section provides two jacks, one for your dry output, and the other for your processed signal. Note that the Dry knob does not change the volume of the signal at the dry output jack; that signal is a buffered bypass version of your original signal.

The pedal's overall bypass circuit is buffered in order to protect signal integrity over long cable runs. A power supply is needed to run the Mono Synth and is provided with the pedal.
