Get Mojo And Style With The Vox VX50KB 50W Keyboard Amplifier

The compact and lightweight VX series is joined by a new 50W model, specialized for keyboard and featuring Nutube, the new vacuum tube. With a coaxial speaker that outputs clear sound even to the high-frequency range, and a bass reflex structure that reproduces rich low-frequency sound with ample power, this amp delivers high-quality sound from a compact and lightweight unit. The three-channel design provides an independent volume control for each channel, and CH3 also supports mic input. This amp can also function as a simple and easily transportable PA system. A full complement of input/output jacks is also provided, including an AUX IN jack, headphone jack, and a LINE OUT jack for connection to a PA system.
