Catalinbread Callisto MkII All-Analog Chorus
Catalinbread · pedal
The Catalinbread Callisto MKII is a 100% analog chorus and vibrato pedal featuring a Mix control capable of full 100% wet or dry signal. The Mix control enables vibrato mode by moving to 100% wet, producing pure pitch modulation without dry signal. Controls include Rate, Depth, Feedback, and Mix for comprehensive modulation shaping. High Rate and Depth settings produce hi-fi chorus while pushed settings deliver tape-like warble and pitch wobble. Feedback creates regenerative, resonant modulation tones. Built by Catalinbread in Portland, Oregon.
