Martin SP's on my Martin DC-16
I've been looking for a good brand for my Washburn - I still have a few sets left of my favorites for it - Washburn used to make strings that had a particular wind to them. Low string noise and they wore forever. I bought a case in about '94 and still have a few sets left (wasn't playing much until 2004 though).

Electrics, I put GHS Boomers .010's on both my Tele and Paul.
