T-Rex Octavius
T Rex · pedal
The T-Rex Octavius is an octave and fuzz pedal (a Tri-Tone Generator) offering octave-up, octave-down and harmony voices that can be blended, used by Mark Tremonti. It produces Hendrix-style octave-fuzz textures plus cleaner octave doubling, suited to psychedelic and hard-rock lead for thick, vocal, octave-laced tones. It is more flexible than a single-mode octave fuzz.
