Celebrating the 25th Anniversary of its renowned Valvetronix series, VOX announces the worldwide release of the new VT20X and VT40X guitar amplifiers. Available now through local retailers and online, these amplifiers are designed for players who want the authentic feel of classic tube amps with the flexibility and precision of advanced digital design. By combining sophisticated new modeling technology with a multi-stage tube preamp circuit, VOX set out to answer the need for an amplifier that delivers the distinctive distortion, touch sensitivity, and dynamic response of treasured vintage tube designs, while offering modern control and versatility for today’s guitarists.
The VT20X and VT40X Classic Blue models are a bold evolution of the Valvetronix concept. Their all-new modeling algorithm recreates the analog circuits of some of the world’s most coveted tube amplifiers at a circuit level rather than relying on simple tonal snapshots. This deep level of modeling allows musicians to adjust gain structure, switch between Class A and Class AB operation, and fine-tune the amplifier bias in real time, producing subtle tonal shifts and responsive interaction that behave like genuine tube circuitry. At the heart of the design is a 12AX7 tube integrated further into the signal path than in earlier generations, delivering enhanced warmth, natural compression, and the kind of “edge of breakup” sensitivity that responds directly to player touch and guitar volume control.
The refined balance between DSP and tube architecture results in harmonically rich tones with smooth clean-to-crunch transitions and expressive overdrive characteristics. Whether dialed back for shimmering clarity or pushed harder for dynamic drive, the amps respond musically, with the kind of sag, bloom, and bite traditionally associated with classic tube amplifiers. This tube-forward approach is complemented by VOX’s advanced VET+ technology, delivering tube realism that feels authentic under the fingers and translates naturally across playing styles.
Beyond their core amp tone, the VT20X and VT40X also offer a comprehensive sonic toolkit for modern guitarists. Players can pair realistic amplifier models with classic effects inspired by iconic stompboxes, creating polished, performance-ready sounds without the need for a large pedalboard. Each amplifier is housed in a tightly sealed cabinet featuring VOX’s proprietary bass-reflex design for extended low-frequency depth and projection, ensuring the amps sound full, controlled, and present in a range of environments.
Thoughtful practicality rounds out the design, making the VT20X and VT40X Classic Blue amplifiers equally at home in rehearsal, recording, or performance settings. Both models feature a USB port for direct connectivity, a built-in tuner, an AUX input for external audio sources, and a headphone output for silent practice. The VT20X delivers 20 watts of power through an 8-inch speaker, offering compact portability with impressive responsiveness, while the VT40X provides 40 watts through a 10-inch speaker for greater headroom and stage capability. As an homage to the original series launched in 2001, each carries the striking Classic Blue aesthetic, featuring a bold split-front design with vintage-inspired blue grille cloth that recalls VOX heritage while presenting a confident modern presence.
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.
