I am looking into this bass, sold my fender so I got some money lying around, want to try a sixer again (I previously noodled on the one owned by a friend, so I could not invest into fixing it up and he didn't want it fixed, so I never really played a good sixer for extended periods of time). Is anyone playing this one, how does it feel? I have never played a 506, but I did play a 500 and it felt great. How's the string spacing? It's my main source of concern. I'm sure it'll sound great. Would be able to make my own conclusions when I try it out in a week or so.
