The Front Panel:
1. INPUT: Connect your guitar or wireless
receiver into this standard 1/4" jack using a
shielded instrument cable.
Channel 1:
2. VOLUME: Set the output volume level of
channel 1 with this control.
3. LOW: Adjust the bottom end response with
this control. The low control covers a range of
16dB at 100Hz.
4. MID: Adjust the midrange response with this
control. The mid control covers a range of 23dB
at 300Hz.
5. BRIGHT: Add a biting edge to your sound by
pressing this push-button switch in. The bright
switch adds 5dB at 5kHz.
6. HIGH: Adjust the high end response with this
control. The high control covers a range of
25dB at 10kHz.
7. CHANNEL: Switch between channels with
this push-button switch. The adjacent amber
LED glows when channel 1 is selected (switch
"out"), the red LED glows when channel 2 is
selected (switch "in"). When a footswitch is
used for channel switching, this switch is dis-
abled.
Channel 2:
8. GAIN: Adjust the overdrive (distortion) level
with this control. With the control towards “0” (to
the left) the signal is relatively clean. As you
bring the control towards “5” (center position)
the distortion increases, along with the overall
output level. Keep turning the control
towards”10” and you’ll increase the distortion
even more.
9. BOOST: Add a third channel (sort-of) by
pressing this push-button switch in. The boost
switch adds 13dB at 1kHz.
10. LOW: Adjust the bottom end response with
this control. The low control covers a range of
8dB at 100Hz.
11. MID: Adjust the midrange response with this
control. The mid control covers a range of 7dB
at 700Hz.
12. HIGH: Adjust the high end response with
this control. The high control covers a range of
10dB at 10kHz.
13. MASTER: Set the output signal level of
channel 2 with this control. At the "0" position
(full left) very little or no signal will be heard; as
you bring the control up (towards center) the out-
put level of channel 2 increases. Use this control
along with your guitar's volume and the Gain
control (#8) to produce a wide variety of sounds.
14. REVERB: Adjust the amount of reverbera-
tion with this control: at the "0" position the sig-
nal is "dry" (no reverb). As you bring the control
up, the amount of reverb increases.
15. PRESENCE: Increase the level of upper
harmonics with this control. The presence con-
trol allows a boost of up to 5dB at 10kHz.
16. STANDBY: This switch activates the ampli-
fier, and should always be turned on last. The
switch lights up when the high voltage power is
passing through to the tubes.
NOTE:
When you first power up this amplifi-
er, leave the Standby switch OFF for at least
20 seconds. This gives the power tubes a
chance to prepare themselves for action.
17. POWER: This switch applies AC voltage to
the amplifier, and should always be turned on
first. The switch lights up when the AC power is
on.
