fOXX Tone Machine
Wow...talk about a flashback! This project sounds almost exactly like the sound samples on the
Tone Frenzy page...just a little different (more aggressive) probably due to the more modern-design transistors. In
my circuit, I'm using four 2N3904 NPN transistors, each with a gain of around 110-120. I have been having some
problems with noise in the circuit, however. It is probably due to the fact that I'm using a power supply that isn't
very well regulated, and it's genrating some pretty loud hum when the effect is switched on, but pretty soon I'm going
to build that regulated power supply that will hopefully eliminate all of the hum problems that I've experienced with
pedals in the past. Overall, this is a very nice project with a classic fuzz sound, and a very good octave up effect.
The octave in this pedal is more pronounced than in the Tycobrahe Octavia. Be careful though, because this project
isn't a beginners project...it can be quite a challenge to wire it up! Before you attempt to build this one, build
some simpler pedals first and work your way up to this...it'll be worth the effort! Below is the schematic of the fOXX
