He said in an old interview (80s) that he used Schecters not because they necessarily sounded better, but because they were more reliable. Back in the day, you either had "old" Fender Strats or new Fender Strats, which weren't very good in those days. Now it's a different story. Better quality, he has his own model, he is also more happy about that vintage Strat sound, hence very little use of Schecters and Pensas. I used to think the Pensa Suhr MKI sounded like the best guitar ever, but these days, listening to Basel or something with NHB, it sounds lifeless.
