Independent shopping perspective
The Korena take
The LPB-3 combines up to 33 dB of boost with three-band EQ in a compact pedalboard format for guitar or bass. Use the Boost control to set gain, then adjust bass and treble or target the midrange from 200 Hz to 5 kHz with selectable bandwidth. An EQ-bypass switch makes tone comparisons direct, while separate switching selects 20 dB or 33 dB maximum boost and buffered or true bypass operation.
Strong match
Who this is for
- Pushing an amp harder for saturated overdrive or raising the level for solos.
- Adjusting bass, treble, and a chosen midrange area within an existing guitar or bass setup.
- Pedalboards needing boost and EQ controls in a compact format.
