Electro-Harmonix LPB-3 Linear Power Booster and EQ Pedal

Inspired by Electro-Harmonix's first effect pedal, the LPB-3 lets you dial in your tone with loads of clean gain and a versatile EQ with sweepable mids.

The effect that launched Electro-Harmonix gets a makeover with the Electro-Harmonix LPB-3 Linear Power Booster. With an active EQ featuring a powerful Parametric Mids control and up to a walloping 33dB of boost, the LPB-3 is the perfect tool for any tone tailoring task. Boost your sound into saturated bliss with transformative precision like never before.

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. The active 3-Band EQ features TREBLE and BASS knobs to control the highs and lows plus a powerful parametric Mids control with adjustable MID FREQ and Q. 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.

This Swiss Army booster pedal's additional features include selectable Buffered/True Bypass switching and internally extended 30V power rails for enhanced headroom.
