Main controls (continued)
LOWS: The LOWS control allows you to adjust the amount of bass pushing the drive circuitry. Increasing
the amount of low end (turning clockwise) results in a thick and raspy distorted sound. Conversely,
pulling the lows out of the drive path (turning counter-clockwise) will reduce the amount of low-frequency
distortion, resulting in a tighter, more defined overdrive.
Fully clockwise, the LOWS control imitates the response of a Marshall ® JTM45 with the bass turned up
(but with more gain than was available from this amp).
Fully counterclockwise, it replicates the tight lows of a modded Marshall ® Super Lead or a higher gain
-type circuit, such as a Trainwreck
Vox ® ® Liverpool. In between these two extremes, the LOWS knob
produces low-end characteristics similar to a Fender -style amp.
®
MORE/PRES: This control combines two parameters, both related to the effects of negative feedback in
the output stage.
Turned clockwise from the centre position (PRES), this control releases the higher frequencies from
the effects of negative feedback, progressively boosting highs just like the classic "Presence" knob on
vintage Marshall ® and Fender ® amps.
Turned counterclockwise from the centre position (MORE), this control progressively reduces negative
feedback in the pedal's push-pull output stage, increasing gain at all frequencies and also varying
playing feel by modifying the break-up characteristics.
With the control centred at 12 o'clock, there is a definite threshold to this transition, with an abrupt switch
from clean to overdriven once you pick hard enough. Turned fully counterclockwise, there's a smooth,
gradual transition from clean to fully overdriven with an earlier onset of distortion.
with the "Presence" knob at zero. Fully

At 12 o'clock, the response is akin to a Marshall
®
counterclockwise, the pedal behaves more like a Vox , with no negative feedback whatsoever.
