[LAU] how record electric guitar?

[Grammostola Rosea]

Hi,

I want to record electric guitar chord progression. I've an:

- epiphone les paul
- little amp, orange 30r
- maudio dmp 3 preamp
- shure 58a beta
- mic stand


What do you prefer, preamp of mic in front of amp?

How do you manage the gain and eq?
- guitar
- amp
- preamp
- ardour


How do you  mix it?
I've read that it is useful to use an low-pass filter, some compression 
and EQ.
What are good plugins on GNU/Linux for this?
What goes pre- and what postfader?

Thanks in advance,

\r
