A very tidy example of the inspiring, super cool Hologram Electronics Dream Sequence Rhythmic Pitch Shifting Pedal. A must own pedal for anyone interesting in exploring uncharted lands with their guitar.
Dream Sequence is a programmable rhythm and octave pedal that uses sequencing, envelope shaping, and pitch shifting to create synth-like arpeggios, pulsating sheets of sub-octave distortion, shimmering, ethereal chord washes, and a limitless number of other new sounds.
