I'm looking for a set of good strings to replace the factory strings on my Aria Pro II P-Bass. I'm looking for a nice solid tone out of them, much like the P-Bass sound you're used to hearing. I just gave it new pickups and will probably be giving it a new bridge and other parts, and I just need a good pair of strings to match. The set that is on them I think is a lighter guage. I really don't know the differences between like light, medium and heavy strings, other than the obvious, so I'd be grateful if somebody could fill me in.
