The thing to keep in mind with a Gretsch is the magic is in the pickups. They use Filtertrons, which give you that unique, jangly sound. The pickups in a T3 are designed to emulate Seth Lover's original humbucker design. That means the T3 will give you more of a Gibson Semihollow sound, like an ES-335.
The T3 is a great playing, high quality guitar. However, if you want to turn it into a Country Gentleman, you'll need to do a pickup swap. FYI -- TV Jones makes some killer Filtertron style pickups -- Highly recommend them.
