Awhile ago I picked up a Cort Curbow 4 from a forumite, a little roadworn but it plays really really nice. I really like the light weight and small body (even though I'm a big guy, 6'5" 240 lbs). It also sounds pretty good, although I think it could be better. I don't want to invest a bunch of money on this bass. I bought it because I wanted a "trunk bass" to go along with my Epiphone trunk guitar, basically an instrument I can keep in my trunk for jamming. I'm thinking of either upgrading the PU or the preamp, whichever will be the most effective. I'm thinking either a bart, a Duncan or an EMG. I'm open to suggestions. Thx in advance.
