The Red Witch Medusa ChorusTrem is an analog pedal that combines two modulation effects in one box: chorus and tremolo, with a combined ChorusTrem mode that runs both at once. Red Witch announced it as a reissue in January 2010, describing the pedal as "Back after five long years and better than ever!"1
What it does
The Medusa covers three ground in one enclosure. Red Witch put it plainly in the announcement: "She'll Chorus, she'll Tremolo and she'll ChorusTrem." The combined mode is the pedal's distinguishing feature, letting a player run chorus and tremolo together rather than choosing between them or chaining two pedals.1
The pedal also offers "multiple modes, everything you remember and more!", according to the company, referring to the modes carried over from the earlier version of the Medusa.1
Connections and control
Two connections stand out for players planning a board:
An expression pedal input means the Medusa can be controlled from a separate expression pedal without bending down to turn knobs mid-song, and the stereo output suits players running a two-amp setup1.
Reissue and availability
The 2010 Medusa was a return: Red Witch described it as back after five years. The company said the pedal would "be available in late February" 2010, with a street price of $349.1
The details on this page come from the January 2010 reissue announcement. The Medusa is a distinct pedal from the Red Witch Medusa Chorus Tremolo listed elsewhere on the site.
Red Witch has built a range of chorus-oriented pedals, including the Red Witch Chorus Em, the Red Witch Binary Star and the Red Witch Empress Deus Chorus. For the wider field, see the site's pages on Chorus Pedals and Tremolo Pedals.
