The V-Stack guitar pre-amp features an authentic sounding vintage valve
amplifier simulator, seamlessly combined with a built-in classic treble
The heart of the V-Stack pre-amp/simulator is an exclusive proprietary
custom analog microchip, which allows a level of circuit complexity, performance,
and power economy simply not possible using conventional discrete circuit
approaches. The extra complexity afforded by this state-of-the-art semiconductor
technology translates directly to a higher precision of the amplifier
The 100% analog circuitry of the V-Stack, like the venerable vintage amplifiers
it is designed to simulate, comprises a pre-amp stage and an output stage
coupled by a tone control network. These stages have been carefully designed,
with the aid of extensive computer simulation, to produce the same harmonic
and sweet overdrive characteristic normally associated with the valve
amplification stages they emulate. This unique sound results from a combination
of asymmetrical and symmetrical signal compression, produced by the pre-amp
and output stages respectively.
Another key component of the V-Stack architecture is a state-of-the-art
low noise/high performance integrated version of a classic treble booster.
Together with the V-Stack's amp simulator capabilities, this feature makes
the V-Stack a portable and self-contained vintage guitar tone solution.
This also means that with the DRIVE control set at or near zero, the V-Stack
can be used as a high performance treble booster.
A built-in speaker cabinet response simulator rounds out the signal-processing
lineup, and provides a final touch of realism for D/I recording purposes.
This produces a similar result to close-miking an amplifier stack in a
soundproof environment, such as an anechoic chamber.
The V-Stack features a "universal" output, having a master level
control to allow the V-Stack to interface to any type of input from mic
level to above line level without compromising tonal quality or signal-to-noise
