The Fuse library is really vast, and very often deceptive.
For example, there is a preset called 80s solo that is popular as hell, but actually just a load of junk.

I'm having great difficulty finding a preset for soloing. I'm looking for a tone to play Stairway to Heaven solo (the "Stairway to heaven solo"preset is a joke) and a tone to play distorted solos like the Fade to Black intro, or Nothing Else Matters.

And the solos that sound crisp and clean, like Chris Broderick's solo in Throwback. (Please listen to that last one, crisp doesn't describe it very well).

They don't have to be from Fuse library, but please only recommend presets you have tried. I'm using an RG421 with stocks and Mustang V2 1.
