Jazzyvee,
The question has never been asked and I don't know if he has ever tried one. He has always been a modifier and is extremely specific about what he likes in an instrument these days. His main axe over the last few years had among other features a hollow resonant body in which the top was floating above the internal structure... He likes a flat fingerboard radius, one pickup in a very specific location, etc., etc... That said, I have heard him pick up and play a generic instrument and make it sound amazing so some day I will drag him to by the factory and make him sit in the front room for a minute. Ha!
