I believe the Starfire is 1.5 at the nut and at that position, it feels like my 62 reissue Fender Jazz. Where it differs from the Jazz is the neck doesn't get a whole lot wider as you go up (kind of like the Ric). It takes me a few minutes to readjust to the scale of the Guild but after that, I've no problems with the neck dimensions and I have large hands.
That said, the Starfire is not my favorite playing bass and a long way from the wide C neck of my 66 P.
Yeah, I love how my 58 AVRI P Bass fills my hand. It’s my go-to.
With this inquiry, I’m not looking for a go-to, but a fun different option.
