I put the SSL-5 Custom Staggered in the Neck, Twang Banger in the middle and a reversed angled body mounted Antiquity for '50s Fender Lap Steel. That is a hell of a combonation. I also have a EC Mid Boost.
Try the SSL-5 in the bridge position, the SSL-1 in middle or neck....and the Fat '50s in the middle or neck. The Fender Gilmore strat has the Fat 50s at the neck position (and SSL-5 in the bridge). I'd try that set up if I were you and come close to Gilmore's set-up and many others. Good luck!
