Classic secondhand pedal from Electro-Harmonix in New York City, this is 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 for superb overdiven tones. The LPB-1 puts impact into your tone. True bypass and tough and compact die-cast chassis. 9V battery (not included) or 9V power cable (not included).
