Few guitar sounds are as unmistakable as a VOX AC30 pushed into its sweet spot by a vintage British Treble Booster. Heard on recordings by icons like Rory Gallagher, Brian May, and Marc Bolan, this pairing helped define the sound of rock’s formative years. The VTB-1 revives that legacy with a re-engineered, road-ready booster that delivers the expressive character of the original without the limitations of 1960s Germanium technology.

Classic Treble Boosters relied on Germanium transistors, revered for their rich nonlinear response but notorious for temperature sensitivity, inconsistent performance, and noise. Simply swapping in Silicon typically loses the magic. So, the VOX engineering team set out to solve the puzzle: How do you preserve everything players love about Germanium while achieving the stability of Silicon?After detailed analysis of multiple original units and months spent modelling their behavior, VOX developed a new approach that captures the wide, nuanced nonlinear region of a great Germanium transistor using a single, carefully biased Silicon device. By widening the edge-of-breakup zone and tuning the operating point with pinpoint accuracy, the VTB-1 achieves the smooth onset of drive, singing overtones, and exceptional volume-knob cleanup that defines classic Treble Booster tone.At the heart of the VTB-1 is a hand-selected Silver Can BC108 transistor, chosen for its consistent performance, low noise, and authentic vintage feel. Modern thin-film resistors further reduce noise beyond what carbon-composition parts of the 60s could achieve.

The sound and feel of the originalsThe VTB-1 preserves the simplicity of the classic single-transistor design while offering a significantly more predictable and stable playing experience. The custom bias circuit positions the BC108 in its ideal operating zone, allowing players to sit comfortably in that expressive edge-of-breakup range.Dial back your guitar’s volume for sparkling, chimey cleans—a hallmark of the best original boosters—or turn the Boost control clockwise to push your amp into a harmonically rich overdrive with massive headroom and focused presence.

Authenticity meets flexibilityBy combining a period-correct voice with modern refinements, the VTB-1 offers an authentic ’60s Treble Booster experience with greatly expanded versatility. The Fat Switch broadens the frequency boost, letting you tailor the pedal to your guitar and playing style, from crisp vintage attack to thicker, more modern punch. And thanks to careful engineering, the VTB-1 remains remarkably quiet, even at high gain settings.

The perfect partner for VOX amplifiers Paired with a VOX AC30 or AC15, the VTB-1 unlocks the singing, harmonically rich overdrive that shaped the golden age of British rock. Dynamic, touch-sensitive, and beautifully interactive, it captures the soul of the original boosters while offering the reliability today’s players need.
