Quick Start
nce you’ve satisfied your primal urge to play, I’d like to suggest you give this manual a chance — it’s been written by a fellow guitar nut and this amp boasts some
killer bells ‘n’ whistles that will warrant your interest. In short, it’ll be worth your
while, we promise. This said, here’s the “Quick Start” — enjoy! I look forward to taking you
through the amp in more detail once you’re done...
HINT: If you’re not sure of the location of a control or switch referred to in this Quick Start
section, you can refer to the illustrations in the section entitled “The Guitarist’s Guided
Panel Tour” (page 7).
ETUP
S
1. Turn the MASTER volume control on the amp all the way down.
2. Plug one end of the supplied power cord into the AC power connector on
the rear panel, and plug the other end into a wall outlet.
3. Plug your guitar into the INPUT jack on the top panel.
4. Turn on the POWER switch.
5. Slowly raise the MASTER volume to a desired level.
HECKING
C
1. Press the top panel PRESET button.
The PRESET LED will light which means you’re in Preset mode.
2. Turn the STYLE selector switch to select a sound style.
For each sound style you select, a preset containing a typical sound for that type
will be automatically selected. The GAIN, VOLUME, TREBLE, MIDDLE, BASS,
and effect settings will be switched automatically.
WITCHING
S
1. Press the top panel CH (Channel) button.
The CH1 or CH2 LED will light, and the program assigned to the corresponding
channel will be recalled (Channel Select mode).
2. CH1 and CH2 will alternate each time you press the CH button.

REATING
1. Press the top panel MANUAL button.
The MANUAL LED will light which means you’re in Manual mode.
HINT: You can also create your own sounds in Preset mode or Channel Select mode.
However, the process is a bit easier to understand in Manual mode, since the positions of
all knobs (except the EDIT 1 knob) are exactly what you’re hearing. In other words, what
you see is what you get!
2. Use the STYLE selector switch to select a style, and adjust the GAIN, VOLUME, TREBLE, MIDDLE, and BASS.
3. If you want to use an effect, use the EFFECTS selector to select an effect
type, and use the EDIT 1 knob to adjust the depth of the effect. For modulation-type effects like CHORUS or TREMOLO, or the DELAY/REVERB effect,
just press the TAP button twice to set the modulation speed or the delay/
reverb time to the corresponding interval — it doesn’t get much easier than
that!
If you don’t want to use an effect, press the BYPASS button. You can edit more
effect parameters but you’ll have to read the manual to find out how.
4. When you’ve come up with a sound you like, write it as described in “Storing your program” (page 15).

TREBLE, MIDDLE, and BASS
This trio of knobs allows you to dial in the exact amount of high, mid, and low frequencies. Also, as you’d expect (and hope!), the exact manner in which each one
of these controls behaves and also interacts with the others is dependant on the
type of sound selected. Turn to the “Sound Styles and Effects” section (page 18)
for more information.
MASTER
This adjusts the overall volume. This setting will vary the amount of distortion created by the power amp.
NOTE: The MASTER volume control is NOT programmable.
NOTE: The GAIN control also affects the amount of distortion. For some settings,
there may be virtually no distortion.

Here you can make settings for effects and noise reduction. For details on each effect,
refer to “Sound Styles and Effects” (page 18).
EFFECTS
Selects the type of effect. You can use the TAP button, EDIT 1 knob and Bypass
button to adjust the parameters of each effect. When you select an effect type, the
effect parameters will be initialized and Effect Bypass will be defeated.
EDIT 1
Use this to adjust the parameters of each effect. By using this knob in conjunction
with the TAP and BYPASS buttons as described below, you can adjust three different parameters.
If the BYPASS LED is lit the effect is bypassed.If you want to adjust the noise
reduction sensitivity you can hold down the TAP button and turn the EDIT 1 knob
simultaneously.
SECTION
•Turn EDIT 1 (without pressing a button) (EDIT 1)
•Turn EDIT 1 while pressing TAP (EDIT 2)
•Turn EDIT 1 while pressing BYPASS (EDIT 3)
NOTE: You can’t adjust the effect parameters while the BYPASS LED is lit.
TAP (EDIT 2) and LED
This button enables you to set the speed of a modulation-type effect such as
CHORUS or FLANGER, or set DELAY times or REVERB lengths; simply press
the button twice at the desired interval.
The LED blinks at the specified speed or time.
HINT: To set the time to exactly match the tempo of a song, press the TAP button several times along with the song.

HINT: You can also adjust the speed or time, by holding down the TAP button and
turning the EDIT 1 knob. (This is the EDIT 2 mode)
NOTE: If the BYPASS LED is lit, you won’t be able to use the TAP switch to set the
time. (The TAP LED will be dark.)
BYPASS (EDIT 3) and LED
If you don’t want to use an effect, press this button to turn the effect off (i.e.,
bypassed). If the effect is bypassed, this LED will be lit.
NOTE: You can’t adjust the effect parameters if the BYPASS LED is lit.
HINT: While the effect is bypassed, you can adjust the noise reduction sensitivity by
holding down the TAP button and turning the EDIT 1 knob.
HINT: The bypass setting is remembered even when you switch modes, switch programs or turn off the power.
HINT: The Bypass button can be used to modify effect parameters (EDIT 3). Press
and hold Bypass and simultaneously turn the EDIT 1 knob. See the chart on page 20
for what parameters can be controlled.
4. PRESET/MANUAL/CHANNEL SECTION
PRESET and LED
This button puts your amp into Preset mode and you can use the STYLE selector
to select a “typical” setting for each type of amp sound. If the PRESET LED is lit,
you’re in Preset mode!
MANUAL and LED
This button puts your amp into Manual mode which means the physical position of
each knob (except for the EDIT 1 knob) determines exactly what you will hear.
This means that the amp will operate just like a conventional guitar amp. If the
MANUAL LED is lit, you’re in Manual mode.
CH (Channel), CH1/CH2 LEDs
This button switches between the two channels and the LED of the selected channel will light. In Preset or Manual mode, the CH1 and CH2 LEDs will be dark. If
from either of these modes you then press this CH button, you’ll switch to Channel
Select mode, and the channel (CH1 or CH2) that you selected most recently will
become active.
WRITE button
Use this button to save a new program into CH1 or CH2. Refer to “Storing your
program” (page 15).
5. POWER SWITCH
When the power is on, the indicator located above the switch will be lit.
