V33-212 Tube Guitar Amplifier with Reverb

5

The Rear Panel

15. AC LINE CORD:

 The grounded power 

cord should only be plugged into a 
grounded power outlet that meets 
all applicable electrical codes, and is 
compatible with the voltage, power, and 
frequency requirements stated on the 
V33-212 rear panel. Do not attempt to 
defeat the safety ground connection.

16.  Voltage Select Switch:

 Set this switch 

to “115” for 120 VAC mains, and to 
“230” for 220-240 VAC mains.

 

With the amplifier power cord 
unplugged

, use the tip of a small flat-

blade screwdriver to slide this switch to 
the proper position.

17. FOOTSWITCH Jack:

 Use this 1/4" 

TRS jack to connect the cable of the 
optional VSFS-2 footswitch. This allows 
for remote control of channel switch-
ing and the boost effect (Tip= channel 
select, Ring = boost on/off).

18. EFFECT SEND:

 Use this 1/4" TS jack 

to send the signal to an external effects 
box.

 

Note:

 The Effect Send jack can be 

used as a line-level output from the 
preamplifier stage of the V33-212 to 
a mixer or recorder. The signal comes 
after the EQ stage but before the 
reverb stage.

19. EFFECT RETURN:

 Use this 1/4" TS 

jack to return the signal from an exter-
nal effects box.

 

Note:

 The Effect Return jack discon-

nects the signal from the preamplifier 
stage of the V33-212, so only the sig-
nal at the Effect Return jack is sent on 
to the power amplifier.

20. EXTENSION SPEAKER:

 Use this 1/4" 

TS jack to connect the amplifier to an 
8 ohm extension speaker. The internal 
speaker remains active when an exter-
nal speaker is connected.

21. SPEAKER 8 OHMS:

 The V33-212 is 

shipped with a cable connected from 
this jack to the internal speakers.

22. REVERB IN Jack:

 The V33-212 is 

shipped with a cable connected from 
this jack to the input of the internal 
spring reverb.

23. REVERB OUT Jack:

 The V33-212 is 

shipped with a cable connected from 
this jack to the output of the internal 
spring reverb.
