I'm going to try to go down and visit Tbird1958 sometime soon and try out his II, see how I feel about them. I'm finally coming to terms with the fact that I'm a Precision bass man, and from I've heard those Grecos are about as close as I'd get in a Tbird. Wider, more Fender-like neck, one pickup with lots of growl in a sweet spot. And that might be the route of it more than just the Precision, I just like one pickup. Barring the Ric and EB-3, which I do like the combo of both on, I only ever use the neck pickups on the Jazz and Thunderbird, and on the Ric I primarily use the horseshoe I'd probably be totally fine with it as a 4000. I really love the way the Bird body feels as far as how it supports my right arm, so it seems like the Greco would be a good middle ground between the features I like in a precision and a thunderbird. Plus, the IIs just look cool all stripped down, and I'd love to refinish one in Ice Blue Metallic.
