It really can sound and feel just like a tube amp.
The Rocktron Velocity 300 Rack Power Amp was designed in a joint effort between Rocktron and integrated
circuitry design engineer Derek Bowers. The Velocity 300 is the first commercially available amplifier to be based on current-feedback
technology. This technology provides extremely high-speed, wide-bandwidth amplification. The bandwidth of the power amp section
is considerably higher than typical amplifiers based on voltage feedback designs therefore providing much more punch and definition
than previous designs have allowed for.
Another of the Rocktron Velocity 300 power amp's innovative features lies
in the reactance simulation circuitry (controlled by the front panel "Reactance" control. At the minimum setting of the reactance
control, the Velocity 300 will provide the added punch and improved transient response of the high-speed current-feedback
design. As this control is turned up, the Velocity 300 will begin to simulate the interaction that takes place between the
tube amplifier and the guitar speaker cabinet.
In addition to the high-speed current-feedback design, the Velocity
300 also incorporates Rocktron's unique "Speaker Reactance Simulation" circuitry. This concept is unprecedented in a solid-state
amplifier and yields the much-sought-after sound of the most impressive tube amplifiers without the added maintenance and
cost and weight of a tube amp.
While other amplifier manufacturers seem to concentrate solely on the harmonic characteristics
of the tube itself (and how to recreate them in a solid state circuit), Rocktron suggests it still lacks the tube sound. When
put to the test and compared directly with the most popular tube amps, these solid state designs still sound cold and thin.
At the maximum setting of the reactance control, the Velocity 300 will instead sound like a tube amplifier, simulating
the interaction between a tube amplifier and a guitar speaker cabinet. The resulting sound is much warmer and fatter, and
when compared directly with a tube amp, is virtually indistinguishable.
