Controls

Blend: Mixes the clean input signal with the overdriven signal. The clean signal remains at unity gain while the volume of the overdriven signal is set by the Level knob, allowing for fine control of the blend ratio.
Level: Sets the volume of the overdriven signal.
Drive: Sets the amount of saturation in the overdriven signal.
Grunt Switch: Sets the amount of low-frequency content to saturate by selecting between three different bass boost levels before the clipping stage.
Attack Switch: Sets the amount of treble content to saturate: The “Boost” setting emphasizes the treble content’s extra clarity and presence. The “Flat” position leaves this register untouched while the “Cut” position will reduce the amount of high frequencies being saturated.
Low: +-12dB @ 100Hz | Low Mids: +-12dB @ 1kHz
Hi Mids: +-12dB @ 3 kHz | Treble: +-12dB @ 5kHz
Low Mids Switch: this switch changes the center frequency of the Low Mids from 1kHz to 500Hz.
Hi Mids Switch: this switch changes the center frequency of the Hi Mids from 3kHz to 1.5kHz.
