Electro-Harmonix has announced the LPB-3 Linear Power Booster pedal, an updated, ultra-flexible update of the brand’s first-ever effect.

Launched in 1968, the original LPB-1 Linear Power Booster was developed while working on the debut Big Muff Pi: engineer Bob Myer built an outboard booster to increase the guitar signal going into the design. EHX founder Mike Matthews suggested running the effect between a guitar and amp – he was so impressed that he launched the pedal as his new brand’s first-ever product.
