How Do I Reduce Hiss On Guitar Parts And Live Reordings?, Logic Express plug-ins Options

[Repo]

How do i reduce hiss on guitar parts and live reordings but still maintain quality sound?
Obviously it helps to have a quality recording in the first place but sometimes i need to take out the background hiss from other samples etc
Any suggestions would be gratefully appreciated on which are the best plug-ins from Logic Express 7.2 for this and how to tweek them effectively?

I don't know what high end studio's you have been in, or what pro's you have recorded with, but I've never heard of anyone recording professionally without a real amp. Digital sounds are ok for work at home, but in a studio, I'm yet to see anyone use solely DI, sometimes they will blend, but never a fully digital sound, and never a solely DI'd sound. Digital effects are nowhere near replacing valves yet. So my advice, if you are recording at home, then DI, if you are planning on gigging, or going to a studio and want to take your own amp, then buy a proper amp. Think about how many famous guitarists endorse certain amps, and then the plug in that comes out sounds nothing like it. For example, take all the guitar plug ins on Logic, none of them are close to a real sound, and in further example, the EVH plug in, sounds nothing like Eddie Van Halen. I've never seen any footage of him with his volume pot fully down, and still loads of hiss. Plug-ins have to create the distortion constantly to produce it, not just distort the signal before it is amplified. This means they will have a lot of hiss and crackle. All of the above applies for distorted guitars, and the majority for clean sounds too. I'm yet to meet any electric guitarist, playing clean, who will not have a preferred valve amp to give his sound that high end sparkly that digital effects cannot.
