Description
Overview
The Electro-Harmonix LPB-3 Linear Power Booster & EQ is a modern evolution of the legendary LPB-1, the effect that launched Electro-Harmonix in 1968. This powerful tool combines massive clean gain with precision tone sculpting, allowing guitarists to push their amplifiers into saturated bliss or carve out a specific sonic space in a dense mix. Housed in a compact Nano-sized chassis, the LPB-3 delivers up to +33dB of boost and an active 3-band EQ for total control over your signal’s character.
Key Details
- Massive Gain Range: Delivers up to 33dB of clean boost to drive your preamp or push other pedals into overdrive.
- Active 3-Band EQ: Features dedicated Treble and Bass knobs for immediate high and low-end shaping.
- Parametric Mids Control: Includes adjustable Mid Freq and Q controls, allowing you to pinpoint and isolate specific midrange frequencies to cut through any mix.
- Flexible Output Levels: A MAX switch allows you to toggle the maximum boost ceiling between 20dB and 33dB, while the Pre-Gain knob fine-tunes the total volume and gain.
- Enhanced Headroom: Internally extended 30V power rails ensure a wide dynamic range and prevent unwanted clipping at high output levels.
- Customizable Signal Path: Selectable Buffered or True Bypass switching to suit your specific pedalboard wiring and cable length requirements.
Use Cases
- Solo Boosting: Use the MAX switch at 33dB to jump from a rhythm tone to a powerful, cutting lead tone instantly.
- Tone Correction: Utilize the Parametric Mids to remove “muddy” frequencies from a dark guitar or add “honk” and presence to a thin-sounding instrument.
- Drive Stage Pushing: Place the LPB-3 before an overdrive or distortion pedal to increase saturation and sustain without changing your core tone.
- Always-On Preamp: Set the EQ to flatten or enhance your natural instrument response and use the Pre-Gain to optimize the signal hitting your amplifier.
Installation
The LPB-3 is designed for seamless integration into any guitar signal chain. For maximum saturation, place it at the beginning of your chain; for volume boosting and final EQ shaping, place it at the end. The Nano-sized chassis ensures it fits on crowded pedalboards. Power the unit using a standard 9V DC power supply. Users can internally toggle between Buffered and True Bypass modes depending on their preference for signal integrity over long cable runs.
Compatibility
The LPB-3 is compatible with any standard electric guitar, bass, or mono-signal instrument. It works effectively with all amplifier types, including tube, solid-state, and modeling amps. It is designed to interface with standard 1/4″ TS instrument cables.
