1. INPUT: Accepts the mono 1/4” plug
of the signal cable from your guitar or
wireless receiver.
CHANNEL A, the distortion channel:
2. GAIN ONE: Sets the signal gain for
the distortion channel, thus controlling
the amount of distortion. Serves as the
“low to medium distortion control;”
accessible through the gain select switch
(#3) or a footswitch. Gives you sounds
from nearly clean to really crunchy.
3. GAIN SELECT: Switches between
the two gain controls (#2, 4). Switch in,
gain two is selected (gain one is disabled)
– both LEDs light. Switch out, gain one
is selected – only the LED under the
word “one” lights. When a footswitch is
used, this switch doesn’t do anything,
but the LEDs work the same.
4. GAIN TWO: Also sets the gain for the
distortion channel. Serves as the “low to
high distortion control,” also accessible
through the gain select switch (#3) or a
footswitch. Gives you sounds from near-
ly clean to screaming dirty. Acts as a third
channel: set gain one for a rhythm
crunch, set gain two for screaming leads.
Be more creative, more expressive;
have more fun!
5. LOW: Sets the level of the lower fre-
quencies for the distortion channel.
Offers a range of 18 dB at 100 Hz.
6. MID: Sets the level of the middle fre-
quencies for the distortion channel.
Offers a range of 10 dB at 1 kHz.
7. HIGH: Sets the level of the upper fre-
quencies for the distortion channel.
Offers a range of 17 dB at 6 kHz
8. LEVEL: Controls the overall volume
level for the distortion channel.
9. CHANNEL SELECT: Switches be-
tween the clean channel (switch out,
LED on) and the distortion channel
(switch in, LED off). When a footswitch is
used, this switch doesn’t do anything.
CHANNEL B, the clean channel:
10. LOW: Sets the level of the lower fre-
quencies for the clean channel. Offers a
range of 25 dB at 70 Hz. Lets you fatten
up the bottom end of your sound.
11. MID: Sets the level of the middle
frequencies for the clean channel. Offers
a range of 14 dB at 800 Hz. Lets you
create sounds from “in the distance” to
“in your face.”
12. HIGH: Sets the level of the upper
frequencies for the clean channel. Offers
a range of 29 dB at 10 kHz. Lets you
add brilliance and crystal clear highs to
your sound.
13. LEVEL: Controls the overall volume
level for the clean channel.
14. BRIGHT: Boosts the upper frequen-
cies when pressed in. Adds a brightness
to the sound. Off in the out position.
15. REVERB, CHANNEL A: Sets the
amount of reverb effect applied to chan-
nel A. Turned all the way to the left (“0”)
the signal is “dry” (no reverb). Turning it
towards the right increases the wetness
(amount of reverb) of the signal.
16. REVERB, CHANNEL B: Sets the
amount of reverb effect applied to chan-
nel B. Turned all the way to the left (“0”)
the signal is “dry” (no reverb). Turning it
towards the right increases the wetness
(amount of reverb) of the signal.
17. FOOTSWITCH: Accepts the stereo
1/4” plug from a two-button footswitch
(such as Crate’s CFP-2) for remote chan-
nel switching and switching between gain
one and gain two on channel A. Ring
controls channel selection, tip controls
the gains. With a footswitch plugged in,
the front-panel switches #3 and #9 don’t
do anything.
18. POWER: (not shown): Turns the
amp on and off, “on” being the UP posi-
tion. The ON LED next to the Excalibur
logo lights when the amp is turned on.
