what is the Fender 8250-5M is designed for ? According to the WWW.FENDER.COM descriptions, they are designed for the thru-body. Could any one here tell me what is the differece between a the string sets for thru-bridge and thru-body? Is it the ball-end? will a 8250 be fit on a through-bridge design? My bass a MIJ Fender 5 string with a bridge something like those on a MIM or a Highway-one series. I have placed an order on the musiciansfriend.com. I need your advice. If the 8250-5M wont work, I will have to cancel the order. Will somebody post a few pictures of the 8250s ball end?
