After doing some research, here at talkbass, (which has help me a lot in my search for a fretless), I have narrow my search to the following 3 basses, but still not sure which one to get, although I am pretty sure the warwick is at the bottom of the list: -Fender Jaco Pastorius signature bass Fretless -Musicman Sterling Fretless with piezo upgrade, is it worth the piezo sytem, i also may add a hipshot detuner at the the E string -Warwick Fretless thumb bolt-on, not quite sure about this one, since I have read a lot about the neck diving problems and that it is really heavy. Regarding the jaco bass would it be worth it to upgrade it with a j-retro preamp, that way I could have the passive sound going on at the passive mode, and if I needed that extra boost I ´ll turn the active mode. I´ll really appreciate your advice and help since I´ll be buying this bass without trying it first. Also if you have any soundclips of these basses that you could email, (firstname.lastname@example.org) or post here, I will be greatly thankfull. I am into jazz, R&B, funk,soul, etc. PD: pardon me for the long post and questions but buying a bass without trying it first its a hard thing to do. Thanks in advance for your replies.
