[olug] Linux as a guitar amp

[A-Wal]

Hello,

    This is going to sound like a really odd question, and I'm not even 
sure it can be done.  However, I'll put it out there just in case you 
guys have an idea or two.

    I've decided to learn how to play the electric guitar, but I'm only 
able to afford a $10 amp from a pawn shop.  However, I have a fancy 
computer sitting here with 5.1 digital audio abilities.  The only 
problem is that I wasn't able to afford a midi guitar, just a standard 
electric.  This means I can't just plug it into my Soundblaster Live 
Drive midi port, and expect it to work.  I've seen in the store some 
kits that allow you to play a guitar on windows using software you have 
to buy, and thought I would try doing it with Linux for free instead.  I 
don't need a recording studio, just the ability to play my electric 
guitar through my PC speakers and possibly tune it using some software I 
can find.  This may be totally impossible without having a midi device, 
but I thought I'd give it a try.  If you know anything about this kind 
of thing then I would be greatly appreciative.

Thanks!
