Get to know them!

Loaded with a multistage 12AX7-driven preamp and advanced VET+ modeling, the Vox Valvetronix VT20X Classic Blue delivers authentic tube tone and a dynamic response that’s truly second to none. This 20-watt hybrid dynamo offers numerous updates from previous VT models, including a redesigned classic Vox split-front aesthetic with a blue grille, improved VET+ circuit-level modeling for lifelike amp behavior, and optimized DSP-to-tube balance for smoother clean-to-crunch transitions. Moreover, the tube-fueled design gives you natural compression and expressive dynamics. Add to that USB connectivity and Vox Tone Room software for deep tone editing, and you get a potent creative hub packed into a compact, gig-ready combo amplifier. Marking a promising revival of Vox’s legendary Valvetronix series, the VT20X Classic Blue melds enhanced tube integration, versatile tones from shimmering cleans to high-gain leads, and a bold visual style into an authoritative sonic powerhouse that leverages cutting-edge digital technology while paying homage to early-2000s Vox designs. Representing a sublime melding of authentic tube warmth and digital ingenuity, the VT20X Classic Blue reintroduces the Valvetronix line to a new generation of players in bold Vox fashion.

A modern evolution of Vox’s game-changing Valvetronix tone

Since their original unveiling in the early aughts, Vox’s Valvetronix amplifiers have been top sellers here at Sweetwater. Beyond that, the VT series, fueled by VET modeling and bolstered by a tube-fueled preamp, proved to be an absolute game changer. The VT20X Classic Blue retains everything players love about the previous VT models, including the revolutionary hybrid design, bass-reflex cabinet design, and seamless software integration, but leverages modern technology to deliver an even better playing experience. For starters, improved VET+ modeling offers outstanding tubelike dynamics and response, providing you with smoother, harmonically richer tones that deliver, in Vox’s own words, “undistorted within distortion” with crunch to light overdrive settings. Moreover, the VT20X Classic Blue’s optimized DSP-to-tube balance reinvigorates its tube drive, delivering a smoother transition between clean and crunch tones when you roll back your guitar’s Volume knob, as well as more expressive dynamics.

High-performance DSP delivers next-level sound quality

Powered by advanced DSP technology, the Valvetronix VT20X Classic Blue delivers exceptional processing power. You’ll hear the difference across its 20 authentic amp models and 13 studio-grade effects. Furthermore, with the ability to save up to 60 presets using Vox Tone Room software, you’ll have instant access to a veritable salmagundi of ear-grabbing, tube-driven tones, complete with a pedalboard’s worth of effects.

Dive deep with Vox Tone Room software

The Vox Valvetronix VT20X Classic Blue’s Tone Room editor/librarian software puts an enormous amount of customizing power at your fingertips. You can tweak parameters to such a degree that it’s almost like building your own instrument. When using Tone Room in conjunction with the VT20X Classic Blue, you gain access to a broad range of 20 realistic models of some of the most sought-after amplifiers around. Sixty preset programs, some modeled after the signature sounds of famous guitarists, unlock the full potential of this feature-laden hybrid combo amplifier. And since the VT20X Classic Blue features class-compliant USB connectivity, you get seamless integration with macOS, Windows, iOS, iPadOS, and Android devices.
