I recently installed a loaded pick guard with a set of Tex Mex pups in one of my favorite Strat builds. I took out a guard with a set of Lace Emeralds (that I really liked). Can't say that I was all that impressed. They sounded thin to me and my ability to tinker with the pickup height was interfered with by the high staggered pole pieces. When I switch pups I always try to get a nice clean sound (through my Princeton-style amp), figuring that the overdrive sound will be OK after that. The pups sounded OK through both a boost pedal and a Bad Monkey overdrive but I could not get a decent clean tone. Not sure how hot these are wound, but I usually find that hotter winds sound better pushed than clean. Jimmie Vaughan uses them, I think, but his brother may have used something with a lower output and then pushed it with the TS. I'll mess around for a while longer, but they may be coming back out.
