Thanks, all! I spent the day playing this Ted and my 2010 Ted. Both are phenomenal guitars. I did notice some slight differences in the model years. Both being IRW Teds, I assumed they would be pretty much identical (with the exception of finish colors.). After closer inspection, a couple of things stand out.
The pickup rings on the '13 match the binding and the pickup height adjustment screws are counter sunk. The bridge has the brass inserts ala my Paul's Guitars. A couple of minor changes but all are well received.
Other than the '13 having a Brazzy board and 57/08 neck pup (the '10 has a 59/09) they are from the same ilk.
Both are so resonant! Sonically, they are very close. The '13 seems to have more pronounced highs and maybe a bit more clarity. Does that have something to do with the bridge or just the sum of the parts? Hmmmm....
Brandon and the boys at Willcutts picked some great woods for these... The wood library guitars are truly spectacular instruments.
