Seymour Duncan SANT P90 B BK

In one word, the SD Antiquities are phenomenal. I've installed these on a Harley Benton CST and I thought the original pickups were good, but I wasn't sure how much the tone would improve with other pickups. Well, turns out it can. A lot.
The CST is now one of the few guitars that I have that work equally well through both my H&K Tubemeister, as well as an Engl Ironball (I'm only talking about lead channel here with everything at 12 o'clock). On the H&K, it's a really sweet kind of overdrive with fantastic harmonics, great sustain and it's really sensitive to picking dynamics. Great for blues and such. On the Engl, the tone is considerably different and turns to something more like a Joe Satriani type tone. It sounds a bit thicker and smoother, it's somewhat less pick sensitive (unless you manipulate the volume control), but in both cases, it sounds absolutely fantastic.
Still not sure whether I'll switch to a thicker sounding bridge pickup, but I think I've found my new favorites. Well done, Seymour Duncan!
