I'm biting the bullet and dropping (to me) a substantial amount of cash on a high-end used fretless. I know there are TB members who can buy and sell me, but I'm a blue collar fella, so... Anywho, it's currently strung with rounds. I don't know what brand, gauge, etc. I worry about this, because I've witnessed a fair amount of vitriol regarding rounds on a fretless. Should I get flats? What brand? What gauge? (It's a fiver). What the heck are half rounds? Tape wounds? HELP!!!
