Hi!
What methods I can use to record a electric guitar?
I mean I have a Fender guitar, a Toneworks Korg guitar procesor, a Marshall guitar amplifier and a creative soundblaster soundcard.
How should I connect them?
Should I use a mic to record from the guitar amplifier?

I connect them like this: guitar -> processor -> soundcard.
It doesn't sound so good.
Maybe I can make it sounds better.
It sounds a little noisy.
Should i put some effects after I record it to the PC(reverb, chorus or something).
If somebody can help me.
I can give nore details if necessary.
Thank you!

The pros won't recommend a Soundblaster card for one.

(this one deals specifically with bass guitar techniques, but you should read it to learn a bit about the need for impedence matching via a DI box)

They should help quite a bit.
Then if you have more questions, fire away!
