Alexander Colour Theory

The Alexander Colour Theory is a sequenced multieffects pedal, allowing sequential morphing between a huge variety of tones, turning any source into an amourphous mass of colorful sound. Offering internal preset memory and sequential control of key parameters for each effect it produces, the Colour Theory brings an unprecedented level of control for effect animation. Offering a choice of pitch shifting, delay (into chorus/vibrato/flanging range), resonant filtering, tremolo, synth effects, and octave effects, the Colour Theory not only provides a huge range of tones, but a huge range of control.

Alexander Pedals Syntax Error, Defender & Colour Theory With Korg Monologue
These three Alexander Pedals all have multiple modes and options for creating a wide range of sounds. The Syntax Error has time and pitch modulating modes as well as a mathematical distortion algorithm. The Defender has overdrive, distortion and fuzz modes. The Colour Theory has effects that are modulated by a built in sequencer. We used a golden Korg Monologue as the input source.
