The Electro-Harmonix Nano LPB-1 Power Booster is spec reissue of the original LPB-1 circuit that preceded and introduced overdrive in 1968. Think of it as a turbo boost for any effect or amplifier. By increasing the gain stage of a signal, the LPB-1 can saturate the tubes on an amp, or add definintion to an effect by placing it prior to that pedal in your signal chain. The LPB-1 gives you extra oompf when you need it! Features at a Glance:

• increases gain stage of the output of a guitar or bass
• allows easy saturation of tube amps without cranking up the master volume or gain control
• enhances effects by being placed prior to effect pedals in signal chain
• a subtle but cool addition to an existing setup
