I bought some flats the other day. Was looking so forward to getting them home and stringing my bass. Well, I got them on and everything sounded great! I got to band practice that night, exited about playing with my new flats. Here's the disappointment... the sound was a horrid, terrible, muddy mess!!! I put the rounds back on when I got home. I packed the flats back up and threw them into a drawer. I'm not sure what I expected. I kept hearing how great flats were. Even the guy at the music store recommended them. Man, what a waste of money.
