Anyone could help me? Thanks a lot! I just ordered Carvin C66 with FT6 fixed bridge, and I want to change pickups to BK,which bridge spacing should I choose 50mm or 53mm, really confused about it, because I can not rule it, it is being built now, and length of leg should be short, right? The C66 is alder body maple top and maple neck and fingerboard, I may choose the Crawler, but Rebel Yell is also good for my ear, which one should be better for the woods combination, first time touching BK, sorry about a lot of questions.
