Well, i think my next bass will be a fretless, partly because ive heard good things and partly because i think it will help my ear. ive never played one, so obviously nothing is concrete, but i was wondering about whether i should go for lines/markings. asthetics aside, which will be more helpful to my development as a bassist? i would think no markings, but maybe that would just be creating more work than i need? And to make this more basses related, what are some good fretless basses to look at? i play mostly rock, metal, and was wondering what some good ones would be. my budget is unclear as this is pretty far in the future, but im thinking 400-600? thanks!
