The LPB-3 features internally extended 30-volt power rails for extended headroom, as well as selectable buffered- or true-bypass switching. The Electro-Harmonix LPB-3 Linear Power Booster is the perfect stompbox for propelling your sound into saturated bliss, and thanks to its active circuitry, you can do so with a level of precision you never thought possible.

You also get a Pre-Gain knob to fine-tune the total gain and volume of your boost. With the LPB-3 on your pedalboard, your too-clean signal will achieve saturated euphoria with a simple tap of your foot.
