V33-212 Tube Guitar Amplifier with Reverb
4
The Front Panel
1. INPUT:
Use this jack to connect your
guitar to the amplifier using a shielded
instrument cable.
2. VOLUME:
Use this to adjust the output
level of the Clean channel.
3. CHANNEL
Select:
Push in this switch
to activate the Overdrive channel. The
Clean channel is active when the switch
is in the out position.
4. GAIN:
Use this to adjust the gain for
the Overdrive channel. With the control
turned counter-clockwise, the gain is
low and very little distortion is present.
As you rotate it clockwise, the gain
increases, producing more overdrive
distortion, and a higher output volume
level.
5. BOOST:
Push this switch in to boost
the output by 10 dB at 900 Hz. This
adds more punch to the midrange fre-
quencies.
6. LEVEL:
Use this to adjust the output
level of the Overdrive channel.
7. TREBLE:
Use this to adjust the output
level of the high frequencies. The adjust-
ment range is 12 dB at 6 kHz.
8. MIDDLE:
Use this to adjust the output
level of the mid frequencies. The adjust-
ment range is 10 dB at 1 kHz.
9. BASS:
Use this to adjust the output
level of the low frequencies. The adjust-
ment range is 8 dB at 150 Hz.
10. PRESENCE:
Push this switch in to
adjust the overall brightness and punch
of the output signal.
11. REVERB:
Use this to adjust the amount
of reverb. Fully counter-clockwise is
“dry” (no reverb). Rotate clockwise to
increase the amount of reverb.
12. LAMP:
This illuminates when the ampli-
fier is turned on.
13. ON/STANDBY Switch:
Use this switch
to activate the amplifier after the On/Off
switch (14) is turned on.
Always turn this switch OFF first, and
ON last! Turn the On/Off switch (14) on
at least 30 seconds before turning on
the standby switch.
During short breaks, you should turn
this switch off, and leave the On/Off
switch on. This will help prolong the life
of the amplifier tubes.
14. ON/OFF SWITCH:
Use this switch to
turn the amplifier on and off.
Always turn this switch ON first and OFF
last! Turn the Standby switch (13) on at
least 30 seconds after turning on the
On/Off switch.
