This is a vintage 1975 Tycobrahe Octavia fuzz octave electric guitar effects pedal. This particular example, serial number 2313, is in excellent original condition! This example sounds absolutely amazing and works perfectly! The schematic design for the original limited production run was based upon an original Roger Mayer Octavia made for Jimi Hendrix. Hands down the best sounding Octavia ever made, it’s no surprise Stevie Ray Vaughan hoarded these gems, owning up to 9 at one point.
The control knobs have been replaced years ago, however, Chicago Iron makes exact spec. replacements, which would restore the cosmetic appearance to resemble an all original example.
