Taking a 1968 classic and giving it a modern makeover, the LPB-3 Linear Power Booster from Electro-Harmonix is a versatile boost pedal that offers up to 33 dB of clean gain. Combined with an active 3-band EQ with fully parametric mid level and frequency controls, you can deftly sculpt your tones and provide the right amount of gain for any application.
Along with adjustable mid level and frequency, you can select a wide or narrow Q (Low/High switch) for the Mid frequency control, offering powerful tonal shaping to cut through any mix. You can select between a maximum of 20 dB boost for dynamics or 30 dB boost for driving preamps to saturation. Pre-Gain lets you control gain levels before the EQ circuitry. And with a high internal operating voltage of ±15V, you get increased headroom, ensuring even more detail in your tone hits your amp, DAW, or PA system with utter clarity. The LPB-3 includes a 9V power supply.
- Treble knob boosts or cuts frequencies above 3.2 kHz
- Bass knob accentuates or attenuates frequencies below 240 Hz
- Mids frequency knob sweeps cleanly from 240 Hz to 3.3 kHz
- 2-way Q switch sets the resonance (or bandwidth) of the Mid EQ, with Low offering a broad Q and High providing a more narrow band for a more peak-like sound
