I've been collaborating with some musicians who have suggested that I aquire a recording interface so that I can record my bass parts to mp3s that they have sent through email - and then send it back. The most affordable device that they have recommended is the M-Audio Fast Track USB. Sounds simple enough, but I'm a novice when it comes to this stuff. I have a PC and a few basses. I have experience as a player, but nothing in the recording territory other than plugging in where I'm told to. Thoughts?
