BLAMMO! Voltage Booster Review

Built on the classic three-transistor design, the BLAMMO! Electronics Voltage Booster stays true to the original Power Boost circuit while adding key upgrades for modern players. The internal charge pump lets you switch between standard 9V operation and a bold 18V mode for extra headroom and clarity. With its Baxandall EQ, you can shape your tone with smooth highs and a full-bodied low end.

Unlike older units, the Voltage Booster guitar pedal features a relay-based true bypass switch for silent operation and increased durability. The addition of a master volume mod makes it easy to dial in overdrive and distortion at lower levels, a game-changer for home practice. Housed in a sturdy, pedalboard-friendly enclosure, this is a vintage-style boost with modern reliability.
