This is a vintage 1975 Tycobrahe Octavia electric guitar effects/fuzz pedal. This particular example, serial number 2951, is in very excellent all original condition and includes the original wooden boxl! 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.
