I tried out a fretless Stingray 4-string today. it had: -pau ferro fingerboard -low action -roundwound strings I liked how the bass felt, but it didn't sound fretless enough for me - the sound I am going for is somewhere between electric and upright (I already play both). This bass sounded like a fretted bass as long as I wasn't doing glissandi or anything. I'm thinking this was because of the pickup configuration - I wasn't able to get too much variety (this is why I play a Fender Jazz). It could possibly be because of the fact that the bass had roundwound strings on it - flatwounds might be the answer. Or else, it could be that the action was too low - I've found that when I raise the action on my Jazz bass, it comes a little closer to the sound of an upright. Or it might be the fingerboard wood. Or maybe it's just how that bass sounds. So, what might it be? Could I get this bass to sound the way I want it to? The reason I'm asking is because I don't seem to have that many choices for a fretless - I'm looking for one I can order without lines or dots, and there are only a couple like that (Music Man and G&L are the only two I've come across in my price range). Although I do like Fender, I tried a couple of fretless Jazz basses and didn't like them. Thanks.
