Gain control for the Crunch channel. This knob determines input sensitivity in Crunch
mode; use it to dial in the desired amount of preamp distortion.
Extremely high gain and volume levels in Crunch mode can produce
powerful feedback. Avoid feedback squeals; they can lead to hearing loss and damage
speakers! At higher volumes, back off the Gain and Treble levels in order to prevent
unchecked feedback!
Single-coil pickups will evoke mildly overdriven sounds at settings somewhere
between 10 and 3 o'clock. Try settings between 9 and 1 o'clock for pickups with high-
output humbuckers or active pickups. Bear in mind the Gain Boost function. You can
activate it via an ENGL Custom Z-9 Footswitch or a preprogrammed MIDI preset to get
an even bigger, beefier crunch tone on the fly.

To help you get acquainted with the preamp's fundamental sounds, I recommend that
you set all tone controls to or slightly higher than the center or 12 o'clock position. For
higher-gain Crunch sounds, your best bet is to turn the Treble Crunch knob down to
prevent the pickups and speakers from generating feedback (a setting in the 10-to -1
o'clock range is recommended).
The Clean and Crunch channels are equipped with dedicated Treble knobs so you can
tweak the top end of each of the two channels separately to suit your taste and the
given sonic scenario. You will find that grittier tones generally sound better with a
touch less treble because preamp saturation makes higher frequencies figure more
prominently in the signal. Bear in mind that you also have the two Normal Bright (9)
and Ultra Bright (10) buttons at your disposal for shaping the high frequency range. I
suggest you get into the habit of dialing in lower Treble settings. That way, you can
program various MIDI presets with one or both Bright options, remotely and have
plenty of tonal variations at your fingertips.
