Need help recording guitar

[Mikeeley]

I am using:

Fostex DMT-8VL recorder
Mackie 1642-VLZ pro mixing board

and i own the following mics:
3 Sm57s (shure)
C3000B (AKG)
C1000S (AKG)

I tried putting the Sm57 in front of my amp and it didnt sound very good. does anyone have any advise they could give to me to make the guitar sound really good?

Im getting a weird, clicking noise everytime i hit a string on the guitar with my current set-up, if that helps at all...

any info would be greatly appreciated, thanks!

Do you use a guitar processor or does your amp have balanced 1/4" outputs. If you have one or the other you could go direct without micing.
