The Sound City Rangemaster Treble Booster is a limited-run, handwired interpretation of the legendary 1960s Dallas Rangemaster, delivering the unmistakable warmth, harmonic richness, and dynamic response of a classic germanium treble booster. Built with carefully selected components, this version features a vintage 1960s Mullard AC107 black glass germanium transistor paired with premium Jupiter capacitors for an authentic vintage-inspired tonal experience.
Designed to push tube amplifiers into rich, harmonically complex overdrive, the Rangemaster emphasizes upper-midrange frequencies while tightening the low end and adding exceptional clarity, sustain, and articulation. From sweet, singing lead tones to aggressive British-style crunch, its touch-sensitive response allows players to move effortlessly between clean and driven sounds using their guitar's volume control and picking dynamics.
The combination of vintage germanium circuitry, Jupiter capacitors, and meticulous handwired construction makes this limited-production pedal an excellent choice for players seeking the expressive character of an original Rangemaster in a compact, pedalboard-friendly format.
