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
Vox ®
-type circuit, such as a Trainwreck
® 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.
At 12 o’clock, the response is akin to a Marshall ®
with the “Presence” knob at zero. Fully
counterclockwise, the pedal behaves more like a Vox ® , with no negative feedback whatsoever.
