Vox VTB-1 Booster Pedal

The Vox VTB-1 revives the legendary pairing of a vintage British Treble Booster and a Vox AC30 — a combination that helped define the sound of rock's formative years and was heard on recordings by icons including Rory Gallagher, Brian May and Marc Bolan. Classic Treble Boosters relied on Germanium transistors renowned for their rich nonlinear response, but notoriously temperamental in use. Rather than simply swapping in Silicon and losing the magic, Vox engineers spent months analysing multiple original units to develop a unique approach that captures the wide, nuanced nonlinear behaviour of a great Germanium transistor using a single, precisely biased Silicon device. At the heart of the VTB-1 is a hand-selected Silver Can BC109 transistor, positioned in its ideal operating zone for smooth onset of drive, singing overtones and the exceptional volume-knob cleanup that defines classic Treble Booster tone.

Roll back the guitar's volume for sparkling, chimey cleans, or push the Boost control clockwise to drive your amp into harmonically rich overdrive with focused presence and massive headroom. The Fat Switch broadens the boosted frequency range, allowing the pedal to be tailored from crisp vintage attack to thicker, more modern punch. Modern thin-film resistors keep noise exceptionally low even at high gain settings, and standard 9V power compatibility makes the VTB-1 a practical and reliable addition to any modern pedalboard.

Authentic Germanium Character From Silicon Engineering

Vox engineers analysed multiple original vintage Treble Boosters in detail, modelling their behaviour to develop a Silicon circuit that genuinely replicates the wide nonlinear operating region of the best Germanium transistors. The hand-selected Silver Can BC109 is biased with pinpoint accuracy to sit comfortably in the expressive edge-of-breakup zone, delivering the smooth compression, singing overtones and touch sensitivity that made original units so musically compelling — with none of the temperature drift, inconsistency or noise of vintage Germanium technology.

Fat Switch & Volume-Knob Cleanup

The Fat Switch expands the boosted frequency range beyond the traditional treble boost focus, giving players the flexibility to tailor the pedal's character from crisp, focused vintage attack to a broader, more modern punch. Combined with the exceptional volume-knob cleanup provided by the precisely targeted bias point, the VTB-1 offers a far wider tonal range than classic Treble Boosters — from sparkling chimey cleans with the guitar volume rolled back through to rich, harmonically saturated overdrive at full boost.

The Perfect Partner For Vox Amplifiers

Paired with a Vox AC30 or AC15, the VTB-1 unlocks the singing, touch-sensitive harmonic overdrive that shaped the golden age of British rock. Dynamic, interactive and beautifully responsive to playing dynamics, it captures the soul of the original boosters in a compact, road-ready and highly reliable package that authentic vintage units — now rare, expensive and unpredictable — simply cannot offer.
