Hey guys, I think for my next bass purchase( in the next few months), I'd like to go with a fretless. More specifically a four string, lined or unlined, doesn't matter to me. I know that it's pretty early to be asking for recommendations as this purchase will probably be in May, but nonetheless, I'd like to see what you guys think, and I like to research a lot before I buy anything. Preferably around the $500 mark. Thanks.
