Main controls (continued)
®
The HIGHS knob provides a continuous range of useful preamp voicings, ranging from a Marshall -style amp with
its tone controls centred (HIGHS set fully counterclockwise), to a late '70s Master Volume Marshall ® (HIGHS at
®
12 o'clock) to a cranked modded Fender amp (fully clockwise).
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 e ects of negative feedback in the
output stage.
Turned clockwise from the centre position (PRES), this control releases the higher frequencies from the e ects
®
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.
