VT20X/VT40X Owner's manual
• The multi-stage tube amplifier circuit in the pre-amp allows the
VT20X/VT40X to reproduce the unique distortion, touch sensitivity,
and the response that is characteristic of classic tube amps.
• The revamped algorithm recreates analog circuits and allows users
to adjust parameters such as the gain and bias (operating point) of the
tube in real time, resulting in an authentic amplifier experience.
• When using certain models, the amp can be switched between Class A
and Class AB operation and, by altering the impedance variation of the
speaker, it can reproduce a sound unique to a tube power amplifier.
• Manage programs and customize amps and effects by using the included
Editor/Librarian software that is compatible with Windows, Mac or iOS.
• The power level control lets you adjust the output wattage of the power
amp.
• Sophisticated modeling technology is used to provide numerous amp
models and high-quality effects.
• You can simultaneously use up to four effects including noise reduction.
• Create your custom sound using the desired amp and effect combination,
then easily save it as one of eight programs (two banks × four channels).
Saved programs can easily be switched from the top panel or with an
optional foot switch (sold separately).
• For each amp model, three preset programs with preset songs are provided
to reproduce the tones of classic hits played by famous guitarists.
• Manual mode lets you use the VT20X/VT40X as a conventional guitar amp.
The physical positions of the actual knobs will be reflected in the sound.
• The built-in tuner allows for easy tuning of your guitar.
• The AUX IN jack allows you to connect an external audio player,
allowing you to play guitar along with recorded music.
