Electro-Harmonix LPB-3
Electro-Harmonix · pedal
The Electro-Harmonix LPB-3 Linear Power Booster expands on the original LPB-1 circuit with the addition of a three-band EQ section including Bass, Mid, and Treble controls alongside the Boost control. This allows frequency shaping alongside the transparent signal amplification, making the LPB-3 useful as both a pure clean boost and as a tonal enhancement tool for compensating for different guitar, cable, and amplifier frequency responses. Suited to blues, country, rock, and any context where clean signal boosting with tonal control is needed.
