If you're getting a second Musicman, a good option could be a two-pickup Bongo 5 or 6. Those things will give you a beefed-up Stingray sound and can be adapted to any kind of music, especially with a 5 or 6 string. And that stealth-black six is truly a thing of beauty. Only negative imo is the price tag; I could never convince myself to buy one because I don't particularly like Stingrays, but it could be just what you're looking for.
