LPB-3

Electro-Harmonix combined three LPB-1 boost circuits into one preamp unit. Three independent gain stages for flexible boosting.

Each channel has its own level control. Use them independently or cascade them together for massive boost. The circuit topology follows the original LPB-1 design.

True bypass switching. Works as a clean boost, a multi-stage preamp, or a three-stage gain device for creative signal shaping.

Three LPB-1s in one box for serious boost flexibility.
