The T-Rex Octavius is a tri-tone octave generator with an added Boost function. The octave-down effect from Hendrix' "Machine Gun," the high octaves of wailing lead tones, and the ability to mix the octaves however you want gives you an incredible ability to build your own signature sound. Vintage warmth gives this octave divider an impressive tone while the Boost gives you the ability to dial in solo or rhythm-level gain.
