VT20X Classic Blue is a compact 20-watt hybrid modelling combo with an 8" speaker, combining Vox VET+ technology with enhanced 12AX7 tube integration for richer dynamics, natural compression and smooth clean-to-crunch response. Finished in a bold split-front Classic Blue design, it delivers authentic Vox character with digital precision in a gig-ready format.

Tube soul. Digital precision. Reborn.
The amp that redefined hybrid tone is back; sharper, richer, and more expressive than ever.

The new VTX Classic Blue takes everything players loved about the original Valvetronix series and pushes it further into the future.
This isn’t just an update. It’s a full-throttle reawakening of the legendary VT tone, with deeper tube response, smoother clean-to-crunch transitions, and that unmistakable Vox attitude now dressed in a bold blue grille.

More tube. More feel.
The 12AX7 is the heart of the sound. With its expanded role in the circuit, you’ll feel the sag, bloom, and bite that only a real tube stage can deliver.

VET+ Technology, refined to perfection.
Born from the research behind Vox’s flagship AC HWR series, VET+ models amp behaviour at the circuit level, capturing every subtle movement in dynamics, harmonics, and tone shaping. It’s not “digital emulation”, it’s amp behaviour, reborn.

A new kind of crunch.
The sweet spot between clean and drive has never felt this natural. Whether you roll back the volume or dig in harder, your tone moves with you; smooth, musical, and endlessly expressive.

Classic blue, modern confidence.
The split-front design and blue cloth bring back an early-2000s Valvetronix vibe — a look that turns heads while the tone does the talking.

From shimmering cleans to roaring leads
The VT-X Classic Blue delivers authentic amp character with the flexibility of modelling.
Dial it in, push it hard, and feel every note come alive beneath your fingers.
