Tube Soul. Digital Precision. Reborn.

VOX’s Valvetronix series has long been celebrated for delivering authentic tube tones through powerful modelling technology. The popular VT20X and VT40X models are now reintroduced with a fresh look and refined sound.

These compact guitar amplifiers combine a multi-stage tube preamp with versatile amp models and effects, offering players everything from sparkling cleans to powerful high-gain tones. The updated design retains the classic VOX Split Front style and now features a blue grille cloth reminiscent of the early 2000s Valvetronix models. With enhanced tone and a more iconic, visually striking chassis, the new VT20X and VT40X continue the Valvetronix tradition in modern form.

Features

• Redesigned front panel with a more classic VOX aesthetic
