Volume and bright booster with a fresh approach to the original Dallas Arbiter Range Master circuit of the 1960s-70s. Built completely by hand using highest quality components.

Comes stock with vintage germanium transistor to nail that authentic vintage treble booster sound. When turned up, adds harmonic excitement in the upper frequencies and a bit of drive, the signature sparkle and cut that made treble boosters legendary for pushing British amps.

Bright and normal switch allows you to get bright boost with or without cutting lows, providing flexibility for different amps and playing styles. Use bright mode for classic treble boost cutting through dense mixes, or normal mode to retain low-end warmth while adding top-end shimmer.

Used regularly by guitar greats like Brian May (Queen) and Jimmy Page (Led Zeppelin). Rich Robinson from The Black Crowes uses his Black Volt Silver Bullet regularly on his pedalboard.

Hand-built in Los Angeles with meticulous attention to period-correct tone and modern reliability.
