The Electro-Harmonix LPB-3 Linear Power Booster & EQ pedal provides a wealth of tone sculpting options for guitarists and bassists. With up to 33dB of boost and a 3-band EQ with parametric mids, you can shape your core tone and push your amp into saturated overdrive. The LPB-3 packs big tone in a compact, pedalboard-friendly size.

Powerful Clean Boost with Precision EQ

The LPB-3 delivers up to 33dB of crystal-clear boost to push your amp into crunchy overdrive or boost solos and leads. Adjust the amount of boost with the Boost knob, then fine-tune your tone with the 3-band EQ. The Bass and Treble knobs provide up to 15dB of cut or boost, while the Parametric Mids section lets you select the frequency range and intensity of the midrange boost. With the LPB-3, you can achieve the perfect balance of lows, mids and highs for your guitar and amp.

Simple Interface, Versatile Performance

Despite the LPB-3's extensive tone-sculpting abilities, it features an easy-to-use interface with clearly labeled knobs. The Boost knob sets the maximum amount of gain boost, from 0 to 33dB. The Bass, Treble and Parametric Mids knobs make it simple to adjust the EQ to your liking. An EQ bypass switch lets you compare tones with the EQ engaged and bypassed. Two additional switches select between 20dB and 33dB of maximum boost and buffered or true bypass. The LPB-3 strikes an ideal balance of simplicity and versatility.

Parametric Mids For Surgical Sound Shaping

The parametric mids control makes the LPB-3 a surgical tone shaping tool. Select the precise midrange frequency you want to boost or cut, from 200 Hz up to 5 kHz, then dial in the bandwidth to broadly or narrowly target those mids. With this level of control over the midrange, you can eliminate muddy tones or bring shimmering high mids into focus. The LPB-3 gives you a new level of mastery over the most important part of your tone.

Compact Pedal, Powerful Performance

Despite its Nano size, the LPB-3 generates an impressive +30V of rail voltage for headroom that won't degrade your tone. Choose between buffered or true bypass switching to maintain your signal integrity in all situations. With the LPB-3, you have a professional grade boost and EQ solution in a pedalboard-friendly size.
