Vox VX50KB 50W Portable Keyboard Amp with NuTube Technology

The all-new VX Series of lightweight, portable and powerful amplifiers from VOX have now increased their ranks, with the inclusion of the excellent VX50KB, a 50 Watt portable keyboard amp featuring NuTube valve technology, and the VX Series' all-new bass reflex structure to enhance those rich and powerful low-frequencies.

Powerful and Lightweight Keyboard Amplifier

Featuring an exquisite three-channel design - one channel of which can be utilised as a microphone intput at the flick of a switch - each of which has an independent volume control. Not only that, but as it weighs only 4.1kg, the VX50KB is a potent and portable Keyboard Amp that can easily double up as a light-weight PA system.

NuTube Technology

The all-new NuTube vacuum tube technology provides the amplifier with it's powerful 50W output, but unlike older tube technology is lightweight and power efficient. Essentially you get all of the intimately rich overtones, clarity and power associated with a tube amp, without any of the back-wrenching lifting usually associated with with an amp of this type.

Optimised Bass Reflex Structure & Extended High-Frequency Expression

The powerful 8", two-way coaxial speaker helps deliver a rich low-range with crisp, clear highs. The clarity of this speaker is such, that every little nuance of your guitar playing will be heard, making each and every performance as individual as you are.

Master 3-Channel EQ System

On the instrument channel you're provided with a Master 3-band EQ of BASS, MIDDLE and TREBLE. These controls help you to perfectly shape your sound in every aspect, letting you dial in those sweet spots for each performance.

The best part of all? Just look at that price! The VX50KB comes at a price that's accessible to all, and would make a sound investment for solo artists or acoustic musicians that are either new to the scene, or just looking for something small-but-powerful to take to their performances.
