Well, if high output is fine with you try a super distortion. I've used them since the 70's and I am not remotely close to being alone in thinking it may be the best hot humbucker ever made. It's tight and clear with perfect balance and that kind of midrange thats transparent and chewy and has all thats good about midrange without any of the bad. Doesn't SOUND middy, but the mids are there and deliver what mids should....body and fullness. Great great pickup IMO. Today i'm trying to go with lower output in my HSS strats but so far nothing beats the SD. I may eventually go back to it again because it's just such a perfect pickup IMO and i can deal with the higer output if i can't find a pickup that sounds as good. Only the output has me looking for something different after decades of using them. I find it hard to believe theres a better humbucker out there if you're looking for high output. The single coil split sound is also much more than just useful, it's great. You truly get a fully usable single coil sound with the jangle and all. I used that abut as much as i did the full HB mode. Do a review search and i'm sure you'll see a lot of people saying the same things i did.
Right now i'm using a duncan thats sounding really good and it may be the first pickup that may be able to replkace the Super D for me, but i haven't used it long enough to be sure. It doesn't sound better, and the lows aren't quite as tight, but it has a lot of similarities and has the lower output i want. But if i was totally ok with the higher output i would still use the super D over the duncan.
