Talk:Octavia (effects pedal)
- I have type-edited this article (removed grammatical errors and unencyclopedic tone), and removed trivial material. One of the paragraphs I removed has no encyclopedic value on this page, but might have a use on another Jimi Hendrix-related page:
The octave fuzz-tone device heard on recordings by Jimi Hendrix was invented and developed by Jim Morris, a brilliant young electronics engineer who was a founding partner in a pioneer concert sound company called Kelsey-Morris Sound, in London during the mid 1960s; Jimi named the device the Octavio. After Jimi’s death in 1970, Noel Redding, the bass player in The Jimi Hendrix Experience, gave the Octavio to Keith Relf, who had formed a new band in 1971 called "Armageddon." The band was in Los Angeles, using Tycobrahe sound equipment, and Relf asked the Tycobrahe engineers if they could fix the Octavio, which had stopped working.

Wasn't this pedal invented by Roger Mayer?
- Isn't describing this people as doing Amplitude Modulation or Envelope Generating is disingenous. It's a Fuzz Circuit feeding a full wave rectifier. It also uses an Transformer which contributes to the sound in terms of low frequency saturation. Q1 is a Common Emitter Amplifier with bypass transistor, Q2+Q3 form a Darlington pair. The 1K pot grounds some of the emitter signal (which is in anti-phase to the signal at the emitter on Q3) and provides negative feedback, when the signal is shunted to ground it amplifier clips creating the fuzz.
