Frequently Asked Questions
Roger Mayer — Hendrix's guitar tech and electronics designer. He created it specifically for Hendrix in 1967.
The high-pitched harmonic doubling of the Octavia is the characteristic sound — most clearly heard on the Purple Haze intro.
Good approximation using NPN silicon transistors, but the original Octavia used germanium. Different feel and cleanup behaviour.
Most effective on single notes above the 12th fret. Lower notes and chords produce a confused doubling rather than clean octave.
