Electro-Harmonix Linear Boost Pre Guitar Pedal

An exact re-creation of the original LPB-1 circuit, which ushered in the age of overdrive in 1968. Put the EHX LPB-1 in front of any effect to dramatically increase definition from its cleaner and heavier input drive. Control the gain and saturation of any amp. The LPB-1 puts impact into your tone. https://www.ehx.com/products/lpb-1/
