I just purchased a four string F Bass on Ebay through The Bass Place in Arizona. Usually I wouldn't consider buying a bass this way, but this thing just looked too good to be true. The real nice thing about it, is the macassar ebony fingerboard, (there almost always maple). I'll post a detailed review when I get it. I attached a link to a picture. I do have one question though. I've never actually played a BN4, (I've only had the opportunity to play BN5s). Can someone tell me what the neck is like on a BN4?
