Designed for bass players who want to engage a realistic synth tone in their rig, the Electro-Harmonix Bass Mono Synth is a stompbox pedal with eleven selectable synth types, each with a different sound. Anything is possible, from the sound of Tom Sawyer to more modern wub-wub-wub dubstep basses. Please note that this is a monophonic pedal; you won't be able to trigger synth chords.

Setting up the pedal is relatively straightforward. The DRY knob controls how much of your original signal goes to the output stage, while the SYNTH knob controls the output level of the synth effect. The SENS knob allows your dynamics to change how and when the synth will be triggered. The CTRL's function changes depending on the synth type, and the synth type can be changed via the TYPE knob. 

The pedal sports one 1/4' instrument input and two 1/4' outputs, one for dry signal, and one for synth. Use the synth output on its own, or route the dry signal to its own input if you'd prefer. Hook your favorite, compatible TRS expression pedal into the EXP jack and you'll be able to control other parameters of the pedal. These parameters, like those of the CTRL knob, change depending on the synth you've got loaded up. 

The pedal sports eleven different preset slots, so you can save your favorite settings into each position of the TYPE knob. A power supply is included with the Bass Mono Synth.
