DISTORT: Imparts a tastefully appointed and harmonically-rich digital distortion whose gain increases as the knob is turned up. When all the way down, the distortion circuit is removed from the signal path.
MIX: Sorely missed in the original, the Mix control lets you blend your pre-Bitters signal in with the output of the Bitters. Turn the control all the way down to hear just your dry signal, turn all the way up for full wet.
DUAL: Turning this up increases the speed of a deep sine-wave phase shifter. Like the original, this Phaser ranges from slow and syrupy to a lightning fast 20Hz, beyond the limits of most phasers. Turning this knob down decreases the rate to 0Hz, which puts the phaser out of the circuit.
BITTERS: The function of this knob is mode dependent, and you can select one of four different programs, listed below. Turning this knob to zero removes it from the signal path.
PROGRAM WHEEL: Each program is listed twice. This lets you select the order in which these knobs occur in the signal path. If the arrow >> is above the text, the order of the programs is "Distortion → Phaser (Dual) → Bitters", while the arrow >> below the text means that the order is "Bitters → Phaser (Dual) → Distortion"
DECIMATOR: Every manufacturer that tapped into this effect type had their own name for sample rate reduction, and this is what Alesis called it. It samples your input signal and lowers that sample rate, which introduces Nyquist aliasing.
BITCRUSHER: This reduces the fidelity of the input signal all the way down to one bit for some true digital destruction. Because this also introduces noise, we’ve applied a noise gate to keep it in check.
FREQUENCY MODULATION: Otherwise known as pitch vibrato, you can dial ours down to a subtle warble (and use the mix control to get a killer chorus sound!) or let ’er rip and tear the signal up like Alesis intended.
RING MODULATOR: Though it sounds like outer space noises, the humble ring modulator is a tremolo with an extremely fast modulation. This introduces additive and subtractive frequencies relative to the input signal and the carrier frequency.
The Bitters accepts a center-negative DC power supply from 9 to 18 volts
