I'm not too sure whether I'd describe them as "Clapton-esque" exactly, but I would suggest looking into Sultans for a "softer stratty blues" tone.
They're sweeter sounding than the ITs were in the same guitar, they encourage me to play with a slightly cleaner sound, but they also really go for Vox overdrive (an AC4TV, no pedals).
I suspect that if I swapped them between guitars with my ITs, that the Sultans would indeed sound very "Just One Night" in my Roadworn (and slightly more Mark Knopfler as well :lol:, the CIJ they're in is very warm-sounding).
In an ideal world I'd be getting more strats and more strat pickups... but I'm very happy with the bases I have covered with ITs and Sultans...
