I have a pair of T-15s as well. 23" scale. One thing about it, you can play some things on it you can't play on a longer scale guitar due to the short reach... I love the Super Ferrites in 'em. In fact, after I get my P-90 Tele done, I'm going to do a Super Ferrite Tele. Super Ferrites are the best of the P-90 and Tele pickups combined. I've got three extra Super Ferrites so I'll probably do a two pickup Tele and an "Esquire."
