Ok, I have just come over this bass. I can get it used, and it's an 3 years old Carvin B4. It's a frettless, (that's what I've been looking for) and it got unmarked frets. It's metallic blue, and has seymore duncan pickups. (Are thay any good?) Anyway, does any of you got any experience with this bass? I'm looking for a rather cheap fretless....How is it compared to the MIM Jazzbass? I can get the MIM Jazzbass new here for about 100 dollars more that what I have to pay for the Carvin....But I love the fact that the carvin is unmarked... Thanks in advance!!
