Did my first recording yesterday at home on my Yamaha Md-4 4-track digital. Piece was a Teleman duet arranged for 2 double basses. Used a Shure Mic (don't have the model handy) straight into the deck. Placed the microphone about 1-foot in front of the bridge, slightly to the left side (g-string side). It sounded horrible! There are obviously some things I can do on the equipment side to improve the sound (better mic, preamp), but my technique needs lots of work before I bother with that. It's amazing how much "extra" noise there was, from hitting strings by accident, finger noise, and screeching from the bow. Listening to each track separately was somewhat pleasing, but the "muddiness" when both tracks were played back was astounding. I think it's what happens when both parts are slightly out of tune. All in all an amazing learning experience.
