Every guitar player seeks the power and playability delivered by a tube amp; the fat drive tone, wide dynamic range, subtle picking nuances, and quick response. After painstaking analysis of guitarists’ tastes and preferences, VOX has focused on the importance of the power amp circuit in creating the sonic characteristics long sought from tube amps. The VOX Valve Reactor was developed out of this power amp philosophy. Based on a 12AX7 vacuum tube, the Valve Reactor circuit at the heart of every Valvetronix+ Series amp perfectly reproduces the operation, subtle nuances, and tonal character of a real tube-powered amp.

One of the greatest advances from previous Valvetronix models is the astounding sense of power generated by the Valvetronix+ Series. The power amp section has the potential to significantly exceed the wattage value indicated by the model name – as indicated by the shaded section of the Power Level knob. The new Valvetronix+ Series also feature a newly re-voiced VOX original design speaker that is sure to amaze you with a powerful sound that you would not expect from a chassis and speaker of this size. These fine Valvetronix+ amplifiers genuinely deliver sonic power that cannot be expressed by mere numbers.

The sense of drive produced in the tube power stage is what defines the inimitably fat and warm tone that's at the core of a great guitar amp sound. Our tube-driven Valve Reactor circuitry is at the heart of recreating this sound. Volume, Gain, and Master Volume controls provide key levels of controlling your gain to achieve a wealth of clean, overdriven and distorted sounds. In addition, these new Valvetronix+ Series amplifiers feature an altogether unique Power Level control. By lowering the Power Level, it’s possible to achieve high levels of gain and distortion at any listening level. And, as was mentioned above, reserve power can also be dialled in using the Power Level control when you really need your amp to scream. The Power Level control allows you to take full advantage of the Valvetronix+ Series potential in any situation.
