Hey everyone, I'm looking for a fretless bass, preferably unlined as I'll be learning upright soon, 5 strings (scale doesn't matter as long as the B is nice and tight), and preferably with an active preamp. I mostly play rock, jazz, and some latin stuff. This will be my first fretless, and I was totally sold on the idea of lines, but after reading some of the threads here on TB, I sorta figured I can make it work sans lines. I already have a jazz bass, and am kinda looking for something with a different, maybe darker, tone. Humbuckers, soap-bars, or a P pickup would be great. I'm fine with new or used stuff, so long as I can find it used (TB classifieds, CL, feeBay). My budget is around $600, maybe a little more later down the road. Thanks in advance everyone!
