Quint Machine is an octave pedal from Danish T-Rex, which also adds the ability to pitch up a fifth.
"Classic octave doubling is cool, but throwing in a 5th up and giving all 3 modulated sounds their own volume control opens up a whole new world. Sound like a 12-string. Sound like an organ. Get rid of your dry signal and sound like a synth just owning that lonely heart. We built the T-Rex Quint Machine to give you more, and it will keep you discovering new sounds for years."
