"Now any electric guitar player can have access to nine magically quirky, dark and unique Mellotron sounds. No more extra devices such as special and cumbersome 13-pin MIDI pickups! In addition to electric guitar, you can trigger the MEL9 with any instrument that produces an electrical output, such as a keyboard or a bass, down to 55 Hz or A1.

The polyphonic EHX MEL9 has superior tracking; you can create single notes or chords with ease. The MEL9 will follow guitar bends, dive bombs, slurs, and any other guitar expression/performance techniques you can throw at it!" -EHX

This pedal is used and in good shape. There is some velcro on the back of the pedal. There are little to no signs of use on the enclosure. This thing rocks! Man, some of these keyboard sounds are an awesome thing to have on your pedalboard.
