Well.......
The first question that popped into my mind as I was reading......you answered before I was done. What style you play. Im the same way. My heart is into low end power groove hard rock, but I also play jazz, classical, some goofy country rip off chops, etc..........
Just my "own" opinion.......the traditional H/S/H works great. Im having a
custom Jem 7 string built with an Evo Humbucker in the bridge, an Evo single coil in the middle, and the new D Activator in the neck. I like my low end power groove rythums to cave in chest, I like my solos to sound like theyre flying thru space at mach 12, and my clean finger pickin stuff to cut glass.
However, a friend here at work, whos into
death metal, prefers straight up blade style humbuckers, some just one at the bridge, some both bridge & neck.
The point I guess Im getting at, isnt so much what kind of configuration "looks" cool or unusual.........but whats going to get you that tone thats in your heart & mind. Further more........I dont necessarily believe its so much "in" the configuration, as much as "whats in" the configuration. Im sure all these things I just said.........you probrably already know
But.......I havent posted here in a few days and this was the perfect topic for me to offer up some blah blah blah

Hope it helped a little............
