A buddy of my son is looking at one of these and asked me a few questions which I could not really give him an answer to. 1. Standard - Music Man® chrome plated, hardened steel bridge plate with stainless steel saddles, or Optional - Piezo bridge with nickel plated brass saddles. 2. Standard - Single Humbucking with Neodymium magnets, or Optional - Dual Humbucking with Neodymium magnets, or Optional - Humbucking/Single coil with Neodymium magnets. I'm a Fender Jazz guy and don't know to much about these baby's.
