Catalinbread Callisto Chorus/Vibrato
The Catalinbread Callisto Chorus/Vibrato Pedal is actually two 100% analogue pedals in one small box. It makes use of a MN3007 Bucket Brigade chip at its core. The Bucket Brigade chip was created between 1968 and 1969, and it was designed to affordably delay an audio signal. The chip was first used in the Roland JC-120 Amplifier, and the Boss Chorus CE-1 pedal, during the mid 70s. The chip has found a useful purpose in modern times as a midpoint between bulky and expensive vintage components, and the sound-converting digital components that audio purists avoid. A wide range of Chorus and Vibrato sounds are possible using the four knob interface. The Density knob continuously adjusts the delay time, allowing chorus sounds ranging from fat to subtle. The Width controls the depth of the effect. The Mix knob adjusts the wet and dry signals. The Rate control adjusts the speed of the effect, from slow and easy to almost a ring modulation. The bright LED On/Off switch is silent, and the pedal runs on either a 9-volt battery or a 9-volt external power supply. The Catalinbread Callisto Chorus/Vibrato Pedal is small, sturdy, and compact, with nice artwork to showcase the look.
