“A bold evolution of Valvetronix”: VOX pairs new amp modelling technology with the “authentic feel of classic tubes” in the new VT20X and VT40X
VOX is marking the 25th anniversary of its Valvetronix series with the launch of two new hybrid guitar amplifiers: the VT20X and VT40X.
Described as a “bold evolution of the Valvetronix concept”, the new models are aimed at players who want the “authentic feel of classic tube amps” and the flexibility of modern digital modelling.

At the core of both amps is a redesigned hybrid architecture that pairs new modelling technology with a multi-stage tube preamp circuit. According to VOX, its new modelling algorithm goes beyond static tonal snapshots, instead recreating the analogue circuitry of some of the world’s most coveted tube amps at a “circuit level”.
This deep level of modelling allows players to adjust gain structure, switch between Class A and Class AB operation, and fine-tune amplifier bias in real time – resulting in more nuanced tonal shifts and a more realistic response under the fingers.
A 12AX7 tube is integrated further into the signal path than in previous Valvetronix generations, contributing warmth, natural compression, and that elusive “edge of breakup” sensitivity that responds directly to player touch and guitar volume. VOX says the result is smoother clean-to-crunch transitions and overdrive tones with the sag, bloom, and bite typically associated with vintage tube amplifiers.
Beyond amp modelling, the VT20X and VT40X include a selection of built-in effects inspired by classic stompboxes, allowing players to build complete rigs without relying on external pedals. Both amps are housed in sealed cabinets featuring VOX’s bass-reflex design, intended to deliver fuller low-end response and better projection despite their compact size.
As you’d expect, the amps are well equipped for modern use. Both feature USB connectivity, a built-in tuner, AUX input, and a headphone output for silent practice. The VT20X delivers 20 watts through an 8-inch speaker, while the VT40X ups the power to 40 watts and a 10-inch speaker for additional headroom. Both are finished in the series’ Classic Blue livery, complete with a split-front design and blue grille cloth as a nod to VOX heritage.
“With deeper tube integration, refined circuit-based modeling, expressive tonal flexibility, and practical player-focused features, the new VT20X and VT40X reimagine the hybrid amp experience for a new generation while staying true to the musical feel that made Valvetronix a favorite among guitarists worldwide,” says Vox.
The VT20X and VT40X are available now, priced at $279.79 and $399.99 respectively.
