1.0 CHANNELS
The tube circuitry of the ATTAX 100 is based on the
innovative, award-winning sound technology first
popularized in the TubeMan. Each of the three chan-
nels drive the ECC83 twin triode tube stages differently
to achieve unique sounds with markedly different cha-
racteristics.
CLEAN:
The ECC 83 preamp tube delivers classic clean sounds
for rich, glassy single-note lines and crisp chord work.
At higher VOLUME knob settings, the "SoftClick" cir-
cuitry produces the soft clip of a vintage tube amp.
The loudest setting where the sound is still totally
clean depends on the impedance of your instrument's
pickups. Generally, the loudest undistorted setting for
the CLEAN channel will have roughly the same volu-
me as the CRUNCH channel at maximum gain.
CRUNCH
Blues sounds a la carte! This channel covers the entire
sound spectrum from clean to overdrive. It is extreme-
ly dynamic. Its attack response enables you to control
overdrive levels via your guitar's volume pot. At higher
gain settings, your tone is carried by lengthy sustain,
ideal for a stinging blues tone with dramatic dynamics.
LEAD 1 + 2:
This channel delivers direct, in-your-face rock sounds.
Switch to the LEAD 2 mode for a completely different
tonal character - even more bottom end, compression
and sustain - in other words, the distinctive perfor-
mance characteristics of contemporary tube amps,
ideal for modern lead playing and heavy-duty power
chord riffing.
REVERB:
The ACCUTRONICS
®
3-spring reverb is renowned for
its excellent sound quality and warm tone. In the sig-
nal chain, the ATTAX 100 reverb section is located
after the FX loop so you can use it for external effects
and still achieve a clean reverb sound. Additionally,
the reverb level automatically adjusts its own level
when you switch between channels, more for clean,
less for lead.

YELLOW CRUNCH LED:
Indicates the CLEAN /

SWITCH setting. The LED illu-
minates when the CRUNCH
channel is active.
EQ SECTION: Common BASS, MID and TREBLE controls for the CLEAN
and CRUNCH channels. MID and TREBLE controls influence each other,
as is standard in tube amps: if you boost the treble, the mids are cut and
vice versa. This sound-shaping feature allows you to dial in a wide
variety of subtle tonal variations.
LOW INPUT: Low impedance
input jack for guitars featuring
humbuckers or active electronics.
It can also be used to achieve a
cleaner signal.
HIGH INPUT: High impedance input for passive pickups/single
coils. It can also be used to achieve more distorted signals.
CRUNCH: Controls the
CRUNCH channel's input
sensitivity and subsequent-
ly its distortion level.
CLEAN VOL: Controls the volume
level of the CLEAN channel.
Depending on your instrument's
pickups, the amp will begin to
clip somewhere around the 12
o'clock setting (SoftClick).
CLEAN/CRUNCH SELECTOR SWITCH: Activates
either the CLEAN channel or the CRUNCH chan-
nel. Once the MSM-1 Module has been installed,
this switching function can be executed via MIDI.
