I am soon to buy a six string, most likely fretless and I want a bass with really great playability, as well as fretless sound. I am leaning currently towards Carvin, because they best suit my budget (up to $2000). I was wondering which Carvin had the best six-string playability and sound, the XB76, the LB76, or the IC6? I like the Icons, but I kind of wanted Koa wood, which leads me to a slight situation. Any help is appreciated, and I am open to any other suggestions. Thanks a lot.
