Vox VT20X Valvetronix Compact Guitar Amplifier - Classic Blue

The Vox VT20X Valvetronix Combo Guitar Amplifier – Classic Blue is a compact yet powerful hybrid modelling amp that blends authentic tube warmth with cutting-edge digital flexibility. Designed as part of VOX’s next-generation Valvetronix series, it delivers responsive, amp-like feel with a wide palette of tones—from pristine cleans to high-gain modern distortion.

At the heart of the VT20X is a hybrid design combining a real 12AX7 vacuum tube with advanced DSP modelling, creating a playing experience that feels natural, dynamic, and highly expressive. VOX’s refined VET+ (Virtual Element Technology) models entire amp circuits rather than just tonal snapshots, resulting in realistic response, harmonics, and touch sensitivity.

With its 20-watt output and 8" speaker, the VT20X is ideal for home practice, recording, and small gigs—offering serious tonal depth in a portable format.

Finished in the eye-catching Classic Blue grille and split-front design, it pays homage to earlier Valvetronix models while delivering a modern, versatile performance platform.
