After a few years of playing, I have decided that it is time to start poking around in the fretless world. I have done some research on fretless basses and played many, although I will admit my knowledge of the different brands and sounds of fretless basses is still limited. It would be great if you guys could offer some suggestions as to which fretless bass I should buy. So far my main choice is Fender's Jaco Pastorius Signature Jazz Bass, although I am considering the Warwick Thumb and a fretless G&L L-2000 Money is not really a concern for me, but I would like to avoid dishing out $3000+ for some custom axe. I would prefer having the neck unlined. Position dots (whatever, you know what I mean) on the side of the neck are preferable so I have some idea of where to put my fingers, but not completely necessary. I have decided to stick to four strings. I would prefer to have a double-octave range on my bass, but it is really not necessary for my tastes. If the bass looks like **** but plays like a dream, I'd buy it. My motto has always been performance over bling. Weight is not a factor. I am a big guy. It also helps when you have a padded elastic strap. Any bass feels almost weightless (although the strap was quite the dent in the wallet .) Again, please offer suggestions of different fretless basses you would recommend. I'm always open to persuasion. Thanks in advance.
