The T-Rex Octavius tri-tone generator works by splitting the signal from your guitar in 3 parts - and then transposing one part an octave down, transposing one part an octave up and leaving the third part where it was. By mixing the 3 signals in different ways, you can create a wide range of rich, thick multi-layered effects.
Octavius lets you get that classic octave-down effect you'll recognize from Hendrix' "Machine Gun" and other recordings. But it also lets you add in a high octave so you can hit your audiences with a sonic wall of three-octave lead lines. You can mix the octaves however you want to create your own signature sound. And the pedal features a controllable boost button to help you lift your solos up above the mix.
