Ok, so over the past few months I have been on a broad search for a new bass. I've come to the conclusion that I would like to get a 5-string (EADGC rather than the BEADG), which would also be fretless (unlined). I'm looking for a bass with really great fretless tone like Jaco that can cut through one to two distorted guitars, but I also would like to have tonal options to go to a thick and fat- bassy tone for walking as well as blues or a reggae feel tune. I play a lot of jazz as well as fusion (Mahavishnu Orchestra, Weather Report, Jaco, etc.) so I need a bass that can give me killer tone but also that has really great playability so I can pull off all those fast runs and odd meters. I will spend up to $2500, put not much more, so I was just wondering what bass would you reccomend for my specific criteria? Thanks guys- all replies are a big help.
