I had a set of the first run of Texas Specials. They're a little differant now...I think the middle pickup might be hotter now so the balance is a little better. They're calibrated differantly than when they first came out. I liked them...but found that I prefered the Duncan SSL-1's, which I found to be brighter, bubblier and more transparent.
Personally, I think the SSL-1's are closer to what SRV used in his '63 Strat because I own a real '63 Strat and the SSL-1's definately sound more like the pickups in my '63 than the Texas Specials did.
The Antiquity Surfers remind me of the pickups in my step brother's '62 Strat, which I always thought sounded a little better than my '63. According to Seymour, those pickups from '62 tend to be stronger than Strat pickups from the 50's and mid 60's. I think he's right.
I don't think SRV recorded anything with Texas Specials...the pickups he used were stock early 60's Fender Strat pickups and according to Cesar Diaz, they were on the weak side: around 6K or so.
