I use Ernie Ball Hybrid Slinkys. The high strings are from a .09 set, but the low strings are from a .10 set. Gives you the needed speed on the highs, and the ability to tune down on the lows without rattle. They also come in pure nickel, but I actually prefer the nickel wound models. I use the heavier low strings, because a lot of alternate and open tunings require you to detune.
I have a Les Paul and '69 Fender Princeton 1x10 Combo (complete with valves, YAY!) I'm all about the Vintage tones.
Oh, and to brighten your tone, use just the bridge pickup, if you haven't already figured that out.
