Octave knob functionality

The Octave knob does not necessarily reduce or increase the octave effect, but changes the character

of it. All the way down, the Q3 transistor is severely loaded in a way that weakens the signal and cuts

highs. This can increase the octave effect or turn it into a glitchy ring-mod type of sound. At these lower

settings, the octave seems to be almost isolated from the main signal, which makes it great for adding

into an otherwise clean sound with the blend knob.

As you turn the Octave knob up, it gets closer to a standard octave fuzz tone, more like the

it's based on. But as with all of these transistor-based octave effects, its behavior will vary

wildly depending on the guitar and the surrounding signal chain.

Octave switch

The octave in this effect is generated by splitting the signal into two, one in-phase and one out of phase,

and then rectifying the signals to cancel out half of the waveform of each. The signals are then combined

back together which emphasizes the octave overtone.

The octave switch lets you disable half of the phase splitter to cancel out the octave effect. However, the

non-octave signal still passes through a series diode (D2) which introduces something called "crossover

distortion". While this crossover distortion is part of the sound of the COB, it sounds very good without

it as well and justifies having its own setting.

As a result, the octave switch has been modified to have Octave, No Octave (original) and No Octave

(modified) settings. Since it's primarily an octave effect, it obviously is going to work best in the Octave

mode, but there are some interesting sounds to be discovered in the other two positions.
