So Eko made a Vox guitar for them and this is what it could do.
My first guitar was and still is a 12 string Eko (bought with money left me by my paternal Grandmother) and they are/were great! Didn’t know they did work for other brands but the guy from Guitars etc says its so. Think he must be wrong on the dates mind you, 1967 is awful early for something that incorporated fuzz box, wah wah and built in tuner with such a range of controls but who am I to say he’s wrong ? . . . . Anyone?
