Introduction
V50-112 Tube Guitar Amplifier with Reverb
Congratulations!
combo amplifier packs a whole lot of vintage tube sound and classic spring reverb into its
compact cabinet, providing you with an amp that is portable and easy to operate, yet still produces incredible sounds!
The V-Series amps offer the versatility required for many different musical styles, and have
the unique tonal purity of a hot-rodded tube amp. The V50-112 is a dual-channel amplifier with
channel switching between clean and overdrive sounds, treble/mid/bass tone controls, global
boost and presence controls, and an internal spring reverb. It cranks out 50 watts of power
from a pair of 6L6GC tubes into a single 12" speaker.

the best components. Each amplifier is tested to confirm that it meets our specifications, and

guitar to the amplifier using a shielded
instrument cable.

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 frequencies.
6. LEVEL: Use this to adjust the output
level of the Overdrive channel.
7.

level of the high frequencies of the
selected channel. The adjustment range
is 12 dB at 6 kHz.

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.
9. BASS: Use this to adjust the output
level of the low frequencies of the
selected channel. The adjustment range
is 8 dB at 150 Hz.
