I don't think he knows what it'll be yet. He told me he'd like to be "the one that gives Gibson their first really successfull signature bass".
But he seemed so totally in awe of the Fender P bass, that I don't think there would be much Gibson character in any Gibson GH Sig...
He's obviously not interested in the Sig being a Thunderbird. He asked me: "can a Thunderbird sound like a P bass?"
No, it cannot. "What if you put Lindy Fralins in?"...
His endorsement with Gibson is a bit strange. He's got a Gibson
Guitar endorsement. They gave him several ES335's. He told me he didn't really know what to think of that...
The entire BCC album was done on a P bass by the way. No effects. Just into a SansAmp and then straight into the desk.
