Building on the success of the popular VHT Special 6 and Special 6
Ultra, the VHT Special 12/20 features increased power (with two power
ranges), a unique preamp specifically designed to excel with pedals and
multi-effects units, a convenient built-in 9-volt DC pedal power supply,
an all-tube buffered effects loop with send and return level controls,
VHT's unique Depth and Texture controls, and variable Watts control.
To optimize the amp for a wide range of output tubes, the
VHT Special 12/20 offers two output-power ranges; safely located behind
the rear panel, a special voltage range switch provides the proper
voltages for 6V6 or EL84 output tubes (in 12-watt low-voltage/low-power
mode). The high voltage 20-watt setting provides the ideal voltages for
higher-power 6L6 or EL34 output tubes. The Special 12/20 ships from the
factory with a pair of 6V6 output tubes (VHT 6V6-to-EL84 socket adapters
are required for operation with EL84 tubes). In addition, the Special
12/20's variable Watts control can reduce the maximum output power to
less than one watt for whisper-quiet volume levels.
The Special 12/20 preamp was designed to bring the most
out of every effects pedal and multi-effects unit with enhanced clarity,
detail, and controlled tube compression. Its low-impedance buffered
effects loop send — with variable send level — can effortlessly drive
the most difficult pedals without tone or signal loss. Thanks to its
variable send and return level controls, the 12/20's effects loop can
accommodate a wide range of pedal or rack effects. Those seeking the
shortest signal path to the output stage can plug their pedals or
multi-effects units directly into to effects return jack — the 12/20's
unique output stage Depth and Texture controls are post-effects loop, so
the output stage characteristics can always be fine-tuned to
accommodate a wide range of instruments, speakers, playing styles and
environments.
As an added convenience for pedal users, the VHT Special 12/20 also features a built-in, regulated 9-volt DC pedal power supply.
