carefully.
Get ready to enjoy the VT20+/VT40+/VT80+/VT120+ amazing guitar sounds!
Main features
• The VT20+/VT40+/VT80+/VT120+ uses Valve Reactor technology, and
features a power amp circuit containing a 12AX7 (ECC83) dual triode valve
(“vacuum tube”) that would normally be used in a preamp. This allows the
amp to produce the true sound and feel of a bona fide all valve (tube) amp.
• Sophisticated modeling technology is used to provide thirty-three different
amps.
•Twenty-five high-quality effects are built-in. You can use up to four effects
including noise reduction simultaneously (or up to five effects if you use
“multiple effects”).
•You can create a sound using the desired amp and effect, and save it in the
memory as one of eight programs (two banks x four channels). Programs can
be switched while you perform, either from the top panel or from a foot switch
connected to the rear panel (Channel Select mode). For each amp model, three
preset programs – Basic, Effect and Song – are provided, giving you a total of
99 programs (Preset mode). The song programs reproduce the tones of classic
hits played by famous guitarists.
• Manual mode lets you use the VT20+/VT40+/VT80+/VT120+ as a conven-
tional guitar amp. The physical positions of the actual knobs will be reflected
by the sound.
• An optional VOX VFS5 foot switch (sold separately) can be connected, allow-
ing you to switch programs or turn effects on/off with your feet.
• The power level control lets you adjust the output wattage of the power amp.
• The built-in auto tuner lets you tune a guitar connected to the INPUT jack.
• The AUX IN jack lets you connect a CD/MP3 player, enabling you to play the
guitar along with recorded music.
