VOX Treble Booster VTB-1 Guitar Effects Pedal

The VOX Treble Booster VTB-1 is a classic British treble booster pedal designed to recreate the expressive gain and harmonic richness heard on legendary VOX recordings. It delivers vintage booster character with modern stability and road-ready reliability.

Classic British Bite Modern VOX Engineering

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 players such as Rory Gallagher, Brian May, and Marc Bolan, this pairing helped define the sound of rock formative years.

The VTB-1 revives that legacy with a re-engineered booster that delivers the expressive character of the originals while overcoming the limitations of 1960s germanium technology.

Vintage Character with Modern Stability

Classic treble boosters relied on germanium transistors prized for rich nonlinear response but known for temperature sensitivity, inconsistent performance, and noise. Simply replacing germanium with silicon often removes the magic.

VOX engineers approached the problem by carefully analyzing original units and developing a silicon-based design that preserves the expressive behavior players love while delivering modern stability and low noise.

Carefully Voiced Single Transistor Design

The VTB-1 uses a single, carefully selected Silver Can BC108 silicon transistor biased to emulate the operating region of the best germanium units. By widening the edge-of-breakup zone and tuning the operating point precisely, the pedal delivers smooth drive, singing overtones, and exceptional volume knob cleanup.

Modern thin-film resistors further reduce noise beyond what vintage carbon composition components could achieve.

The Sound and Feel of the Originals

The VTB-1 preserves the simplicity of the classic single-transistor treble booster while offering far more predictable and stable performance. The custom bias circuit places the BC108 in its ideal operating zone for expressive edge-of-breakup response.

Rolling back the guitar volume produces sparkling, chimey cleans, while turning the Boost control clockwise pushes the amp into harmonically rich overdrive with massive headroom.

Authenticity Meets Flexibility

By combining period-correct voicing with modern refinements, the VTB-1 delivers authentic 1960s treble booster experience with expanded versatility. The Fat Switch broadens the frequency response, allowing tones ranging from crisp vintage attack to thicker modern punch.

Thanks to careful engineering, the pedal 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 defined British rock golden era. Dynamic and touch-sensitive, it captures the soul of the original boosters while meeting the needs of today players.

Iconic Tone Within Reach

Authentic vintage treble boosters have become rare, expensive, and unpredictable. The VTB-1 brings their unmistakable sound, feel, and musical response back to modern pedalboards with refined stability and road-ready performance.
