EHX™ LPB2™ REPLICA COMPLETE KIT

A complete kit for the CB1, our replica of the vintage Electro-Harmonix™ LPB2™: a great sounding, simple, clean booster.

About the effect

The Electro-Harmonix™ Linear Power Booster came in two forms: the LPB1™ plugged straight into the guitar, and the LPB2™ was a stompbox. They share the same circuit and differ only in enclosure and switch. The original LPB1™ was wired point-to-point, with parts held mostly by their solder joints. Our CB1 (Clean Boost 1) is a stompbox version like the LPB2™, on a proper PCB.

A popular modification moves the volume control to the front of the circuit, which tames harsh distortion; schematics and layouts for this input volume version are on the project page along with other mod notes.
