HANNEL DESCRIPTION
The preamp of the Quad 15 consists of four channels, each with 3 modes for a variety of clean, compression, overdrive
and distortion characteristics. This section describes the individual controls of the channels and how they sound. Visit

LEAN C
HANNEL
A simple independent 3 knob clean channel with a variety of sound characteristics. Dynamic and clean at lower volume
settings (< 11:00), and as you turn up the volume you enter the compression/overdrive territory that will help your clean
sound stand out in the mix. The power attenuator (see page 14) lets you set the desired listening level when turning up
the volume control for compression/overdrive. At lower volume settings, this channel provides full dynamics for super
clean sounds and use with classic distortion/overdrive pedals.
BASS RES:
Bass resonance control
Most guitar amplifiers offer only the classic “tone-stack” bass control, which can sound muddy if you
turn it up to add body to your clean sound. The individual bass resonance control for the clean channel
lets you add body and thickness to the sound while retaining clarity. Oppositely, if your guitar suffers
from boomy bass, the bass resonance can be turned down to tighten up the bass.
Tone/mid:
3 way switch for different clean tones
High:
Mids and Highs boosted
Lots of mids and sparkling highs. Works well with guitars with strong bass response,
humbuckers or single coils. A boomy neck pickup can be tamed, while the bass resonance
can be boosted for a more full and wet clean sound that easily goes into overdrive.
Low:
Mid dampened
Natural sounding. Works well with most pickups with moderate settings of bass resonance and treble.
Adds more boomy bass to thin sounding guitars.
Scoop:
Lower mids scooped
(300 - 500 Hz)
Guitars with too pronounced lo-mids for clean sounds will benefit from this setting.
High output humbuckers have a tendency to sound boomy or honky tonky when played clean. Using the
“Scooped mids” setting and adding more Bass resonance will result in a more full and balanced tone.
VOLUME:
From clean to power amp overdrive
When turning up the volume, some asymmetrical compression/overdrive is added by the following
preamp tube before the power tubes go into overdrive. Both live and in the studio, turning up the
volume just before the power tubes start to distort, gives a thick and compressed sound that cuts
through, and is easier to work with for the sound engineer.
NOTE! Turning up the volume into heavier power tube distortion, makes it difficult to match the levels from the
other channels.
