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 gain 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 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

Low Mids

: +-12dB @ 1kHz | 

Hi 

Mids

: +-12dB @ 2.8kHz |

Parallel Output

: Hardwired copy of your input signal, useful 

for getting a clean signal in recording and live situations

Direct Output

: A balanced version of the ¼” output, useful for 

running into PA’s or studio mixing consoles.
