Electro-Harmonix

Electro-Harmonix (EH) was established in 1968 by Bill Berko an audio technician and Mike Matthews. Matthews has a Bachelor in electric engineering and a Master in management and worked three years with IBM before starting his own company Electro Harmonix.
Matthews still works for his company and is a Rhythm & Blues piano player in his spare time.
Electro-Harmonix got famous for its guitar effect pedals like the Linear Power Booster or LPB-1 and later on the Big Muff which has been bought also by Jimi Hendrix in ’69.
The LPB-1 is still manufactured by EH. It’s a relatively simple design with one transistor and a 9 Volt battery as its current source.

In the seventies EH introduced its Freedom Amp that needed no AC as its power supply but carried 40 ‘D’ class batteries. As a musician you could play everywhere freely because AC wasn’t needed.
