The Medusa was originally made in a small batch of 73 hand-made units in 2003. Discontinued for seven years, the decision to reissue came as a result of several hundred emails from players requesting production to restart. Re-released in 2010, the Medusa offers guitar players the unique functionality of a chorus unit and tremolo unit in the same enclosure. The Medusa offers a totally unique function – chorustrem – where the chorus modulation pulses at the same rate as the tremolos throb. Swirling Chorus! Pulsing Trem! Inspiring Chorus-trem! Fans of the Medusa include David Catching (Queens of the Stone Age, Eagles of Death Metal), Galen Henson (Joe Satriani), and Saskia Hahn (Peaches).FunctionsIndependent Chorus and Trem100% analog – uses original MN3007 BBDUnique Chorus-trem effectStereo OutputExp pedal outputTrue bypass9 volt battery or DC 9 volt wall wartSpecs: Current draw: 49maWeight: 405 gramsDimensions: 118 mm x 38 mm x 94 mm.
