First off, I did search this topic, but couldn't find an answer. I have an SX P bass and an OLP MM2 both with Seymour Duncan pickups. I'm looking to replace one or both of the bridges with a BA II, but I'm not sure which one I want to replace. I'm thinking the OLP, but I'm not sure. Will it make an adequete difference on both of them? Second, do I need to notch the saddles or could I get by without doing so?
