      Rocktron Velocity 300 150W Rack Power Amp (105806244)
Availability:  


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. In addition, the Velocity 300 has “Definition” controls to give you that little bit of edge you need to bring your playing out in the mix. It also has automatic short circuit protection, which detects problems and shuts down the amplifier before any internal damage can be done.


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.

    As reviewed by Dylan on 6/24/2010

    A great piece of gear. Easy to use and equally easy to get a good tone when combined with a decent preamp. I use a Pod X3 Pro running stereo into the Velocity through a 4x12 stereo cab and I love it. Getting good tube-like tone is simple with the reactance control which really warms up the sound and adds good punch to the low end. With the stereo and mono bridge options, it is easily compatible with most cab setups. If it were stolen I would definitely buy it again. 1 rack space and ample power with all the setup options this unit allows make it a worthwhile purchase. Only thing I don't know is how well it cools itself as it is a new purchase, but from most things I've read, this is not an issue for the Velocity. Definitely consider this product. Top of my list as far as solid state power amps go.

  • Clean, Crisp and Powerfull.

    As reviewed by John on 8/17/2011

    I'm using this power amp behind my Digitech GSP1101. I can't tell you how much it woke up my system. My sound has never been better! Wish I bought this sooner.

  • It Works

    As reviewed by Cameron Pierre on 10/30/2012

    My Digitech GSP 1101 has finally come alive after experimenting with different speaker setups for years I finally took the plunge. Up to this point I had been using a Tubeworks MosValve MV 962 power amp which is a fantastic amplifier in itself, but always felt that something was missing. Enter the Velocity 300. It actually does everything it says on the tin. I am running it into a pair of 1 x 12 cabs loaded with EVs. Rocktron's unique "Speaker Reactance Simulation" circuitry makes a huge difference to the overall sound of the power amp. So far I have gigged it with no problems for 8 months and loving it.
