V50-112 Tube Guitar Amplifier with Reverb

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.

Select: Depress 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 frequen-
cies.

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

8. MIDDLE: Use this to adjust the output 

level of the mid frequencies of the 
selected channel. The adjustment range 
is 10 dB at 1 kHz.

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.

10. PRESENCE: Use this to adjust the over-

all brightness and punch of the output 
signal.

11. REVERB: Use this to adjust the amount 

of reverb for the selected channel. 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.

 

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.
