Hello everyone,

I'm trying to get my electric guitar connected to my sound card.

Keeping the card's input gain low keeps away the noise, but
produces a very low signal. I can put Jamin right after that and crank
up the input gain, but there's a maximum to it and I'm not sure whether
that's the right approach.

Turning up the card's input volume increases the gain, of course, but it
delivers a lot of very ugly noise as well. If I connect a microphone to
the port, I get a high-gain signal without noise.

The card's an SB Live! Platinum, and the mic port seems to be the only
capture port usable by Jack. The cabling for the guitar is all new.

I can provide samples of the input signal at the various settings if you
wish.

Leslie
