The Foxrox Octron3 is an analog pedal - not to be confused with a digital octave pedal. You won't get that cheesy harmonizer sound with digital latency. Instead, it's an organic analog effect that responds to your playing style/technique. And it takes on a new life when you put it through other effects and crank it up. Octave up, down, clean with a little of each mixed...you can dial in just a hint of octave or you can make Octron3 your octave monster!
Octron3 is smaller than the original Octron and has two additional switches. These switches bring the original Octron's internal settings to the front panel. Aside from that, Octron3 uses the same circuitry as Octron. The switch selections have been fine-tuned to bring out a choice of Octron’s best sounds, previously not possible without opening the unit.
Octave Down - It's an octave divider in the tradition of Mutron/BOSS OC2/DOD Octoplus/etc. It tracks your dynamics and has more pre-divide gain and filtering. The result is probably the best tracking you'll ever get from an analog octave divider. Ultimately, the tracking is most dependent on playing technique. Articulate playing tracks well, while sloppy playing doesn't.
Octave DOWN Mids/Low switch: Mids - This gives the low octave a "woody" type of tone, with midrange punch that will cut through when using a small amp. Low - This gives a deep, fat bass tone that sounds HUGE through 12" and 15" speakers. Frank Marino helped in shaping the fat low octave sound. (Frank Marion and Mahogany Rush)
Octave Up - It's a high gain circuit that uses a pair of germanium diodes to get the octave doubling effect. The upper octave is present at all parts of the neck, but it becomes most prevalent as you go up the neck on the high strings. Up around the 10th fret and higher, you can get a pure upper octave.
Octave UP Bright/Pure switch: Bright - The octave up circuit receieves a full range signal and the output is bright and clear, and rich with harmonics. Roll your strat volume knob down and use the neck pickup for Hendrix "Octavia" type sounds.
Pure - The octave up circuit recieves its signal after going through a low pass filter. This results in a more pure octave-up sound, with less treble and fewer harmonics.
