Hey, I currently have an OLP MM2 which is totally stock and i'm considering upgrading it. I got thinking the other day though, how much more it would cost to get a musicman s.u.b. instead. The subs go for around $649 new, what do they go for used approximately? The OLP on the other hand would be around $200 to upgrade just the pickup and add a pre-amp (the seymour duncan set costs around $200 i think). So for a little more i could just buy a s.u.b. Are the subs that much better than an OLP? Would it worth it saving a little more and splashing out for the sub instead? How close do the subs get to a genuine stingray too? What would be a reasonable price to pickup a used 4 string sub?
