Thanks for the explanation. It's not something I'd consider easy to do, 
my soldering/electronics skills aren't up to that!

A friend gave me a DI box that has amp modeling and other capabilities, 
but it does have one feature I've used many times. Gain control. Plug 
the guitar into it's guitar input, leave everything else at neutral (no 
amp modeling), and adjust gain until it's output is right for line input 
to my little USB card.

I bought a contact mic for the guitar that outputs electric guitar 
levels but haven't tried it yet with my classical guitar. I wonder what 
a classical guitar might sound like going through Guitarix?
