The nut is standard so are the pick ups the bridge I got from Ebay advertised has Gold Music Man OLP Style Bass bridge BB-MM4-G.
It's far better than the one you get in the kit because the saddles screws are longer. I was thinking of doing a sound demo maybe in a week or so. I've played it at a gig and was very impressed with it. So now it's going to be my main Bass. There is nothing better than playing something that you have made. Love Love Love it.
