Can't you swap the plate for one of the more traditional bent plate ones? Those kinds of bridges are pretty cheap... I'm surprised the guys at the shop didn't just sell you one.
Actually, he did offer to sell me a new bridge that a bridge cover would fit over. But apparently, the bridge on my CV Jazz is slightly bigger than the standard fender bridge (it was an allparts fender replacement bridge that he used to compare). He claimed that installing this new bridge would affect my string spacing- can anyone confirm or deny that? Thanks a ton.
