“I am about to delve into P-90 world pretty hard... whenever I pick up a guitar with P-90s in it I get some inspiration”: Warren Haynes says he has been working with Gibson on two prototype signature guitars and one is a Firebird with three P-90s

Warren Haynes of Gov't Mule plays his non-reverse Firebird onstage in Italy, with a Soldano SLO-100 tube amp in the background.

Warren Haynes says he and Gibson have been working on a pair of signature guitars that are at prototype stage, and they will present a change of pickups – and expanded range of tones – for the Gov’t Mule frontman and former Allman Brothers Band guitarist.

Speaking with American Musical Supply, Haynes says he is working on a Les Paul and a Firebird, both of which will see him swap humbuckers for P-90s, and he says the change will do him good.
