Stevie Ray Vaughan played Stratocasters. He had one from about 1954 or so that was beat to hell, with no finish left above the pickguard, as he'd worn it away with his extremely aggressive style of hitting the strings. That one was named "#1", IIRC. His cleaner one was white, and he'd named it "Lenny" after his first wife. When they divorced, he changed the name to "Scotch". I don't know what he called it after he gave up drinking.
He used heavy strings--11 or 13, 15, 19, 28, 38, 58 instead of the usual 9 or 10, 13, 17, 26, 36, 46--which gives a richer, throatier sound. It also lessens string breakage, which helped with the bends he did so often.
He used a lot of different brands, but I see GHS Rockers mentioned a lot. They have a nice sound. I've tried quite a few different brands and gauges of strings. The standard size strings are a lot easier to play. By the time I finish a song with the 13 to 58 strings, both hands ache.
