I've had major GAS for one of these for awhile, but have a couple of questions. First, originally the specs indicated abalone dot position markers, but apparently these have been changed to black markers on the maple fretboard. Are they abalone on the rosewood? Fender's site doesn't specify. Also, the specs indicate an "asymmetrical" neck profile, and a 12" radius fretboard. Does it feel dramatically different from a typical U.S. Fender Jazz bass neck? If so, how? (If a description is possible. It's been impossible to find one to test in my area.) I'd appreciate any other comments on the RBIV, as I haven't found an in-depth review.
