Electro-Harmonix got its start way back in 1968 by its founder Mike Matthews. Mike is considered the Godfather of effects pedals.
So many ground breaking albums were made with Electro-Harmonix pedals. Each generation of musicians has discovered how great they are.
Start with the Big Muff fuzz pedals then expand your way into other greats like the Memory Man, POG and the new Intelligent Harmonizing pedals.
