What do you like for good clean tones? Today I have spent a good amount of time on youtube listening to various emulators, most notably the Tech 21 sansamp character series.

When I listen to these demos, the thing that really strikes me is how dead the plain, (presumably) non-EQ'd guitar tone is. When the pedals are engaged, even on clean tones, it can make a big difference.

I have found on my own Sansamp GT2, I like the california clean (i.e. no gain) a lot more than I thought I would. When I think of mesa, uber high gain generally comes to mind, so this has been a bit of surprise for me.

Just curious what you guys and girls like. Fender? Vox? Mesa? Does Marshall even have a clean tone (kidding!)? What is it that makes a good clean tone sound good? Is it all EQ (i.e. boost high end or whatever), or is there some harmonic junk happening there too?
