Grazie per il link @emadb!
A name that I’d like to share Is Paolo Tofani: guitarist of the italian experimental jazz-rock band Area.
He was a friend and collaborator of Peter Zinovieff of EMS; One of the very earliest use of a “synth-guitar” was made indeed from Paolo’s experimentations: he connected his Gibson doublecut to a synthi AKS via some special pickups (later evolved in a dedicated synth prototype IIRC).
You can hear that on the main riff of Luglio, Agosto, Settembre (Nero), starting at 01:05.
I don’t remember if I read It in a interview or was just an old rumor but it seems that Paolo was contacted by a young Brian Eno to play whit his newborn band Roxy Music; But he decided to leave London and came back to Italy to form his own project, Area.
