The Electro-Harmonix LPB-3 Nano Linear Power Booster is a powerful analog boost and tone-shaping pedal designed to make your guitar louder, fuller, brighter, or more prominent in a band mix. Released in 2024, it updates EHX's original LPB-1 booster concept with a sophisticated three-band EQ, adjustable parametric mids, and up to 33 dB of boost.

Unlike a modulation pedal such as the Good Vibes or Neo Mistress Flanger, the LPB-3 doesn't create swirling or wavering effects. Instead, it focuses on gain, volume, and tonal control. You can use it to give a clean amp more presence, push a tube amp into overdrive, add body to thin pickups, or make lead guitar stand out during a solo.

What does it sound like?

• Clean volume boost: Makes your guitar louder while retaining much of its original character.
• Amp overdrive: Pushes the input of an amplifier harder for more saturation and sustain.
• Thicker, fuller tone: Adds bass or low-midrange weight to thin-sounding pickups.
• Cutting lead tone: Emphasizes upper mids so solos stand out in a dense mix.
• Brighter, clearer sound: Reduces muddy frequencies or adds treble definition.
• Studio tone shaping: Adjusts the guitar signal before it reaches an amplifier, recording interface, or other suitable equipment.

The LPB-3 has internally boosted power rails designed to provide extra headroom. Although it can deliver substantial clean gain, pushing the level into an amplifier can still produce natural clipping and distortion.
