Electro-Harmonix Refreshes its First-Ever Effect with the LPB-3 Linear Power Booster & EQ

Before there was Muff, there was boost. The LPB-1 Linear Power Booster was originally discovered by EHX founder Mike Matthews while working with engineer Bob Myer to develop the very first Big Muff Pi pedal for Electro-Harmonix. Bob had overestimated the output of guitar pickups and built an outboard booster to boost the guitar signal going into his original circuit design. Curious about the little box hanging off of the Big Muff, Mike asked Bob show him what would happen if only the booster box was used with the guitar an amp. The resulting volume levels blew Mike away and he knew he had his first product. Over 5 decades and millions of pedals later, Electro-Harmonix is proud to introduce their latest Linear Power Booster & EQ, the LPB-3.

Housed in EHX’s Nano-sized chassis, the LPB-3 is capable of boosting up to +33dB of clean gain with the powerful tone shaping of a 3-band EQ with parametric Mids. BOOST sets the overall output of the pedal with the MAX switch toggling between 20dB and 33dB of maximum boost. Use the PRE-GAIN knob to fine-tune the total gain and volume of the boost. The 3-Band EQ features TREBLE and BASS knobs to control the highs and lows plus a parametric Mids.

This Swiss Army boost pedal’s additional features include selectable Buffered/True Bypass switching and internally extended 30V power rails for enhanced headroom. The EHX LPB-3 comes equipped with standard EHX 9 Volt power supply, will be available in JUNE 2024 and have a U.S. Street Price of $129.00.
