I always loved the sound of the Mellotron on Beatles, King Crimson, Genesis and so many other great albums. When I saw EHX actually made one in pedal form for guitar I jumped at it and have used it for mystical melody lines and backing tracks with great success. Only used in studio, kept in top top shape and never gigged, here is your chance to explore! Sounds just like a Mellotron and tracks really well on guitar --so much better than most of those synth pedals. Runs on 9 volts with heavy duty EHX 9v adaptor included. Fully polyphonic: does chords, harmony fingerings and single-string melodies of all the instruments of the standard Mellotron. Strings, cello, clarinet and orchestra are my personal favorites. Extremely easy to use right out of the box. Records great but many use it live. $135 plus shipping.
