just try doing your own thing...
Really. I have one specific tone that I use for absolutely EVERYTHING. (Well, one clean, and one distortion.) But one thing I've found to be very similar to JP's tone is adding just a touch of delay to the sound. It really makes your sound much fuller, especially when you're playing solo.
But yeah, using one tone for everything makes it seem a lot less like emulation (which can be good and not so good) and makes it more original.
