Sorry, but that wouldn't do it for me. I put an East MMSR circuit into a 2007 Stingray 5 once, and it did improve the tone, but if I was to replace the circuit in a Special with a two band, then I'd need to replace the frankly rather characterless Neodymium pickup they put in it with an Alnico, lacquer the neck, fit a chunkier bridge, and string it through the body. (OK, maybe not the last one!) I don't disagree that the fit, finish and feel of the Special is very nice (I briefly owned a Special 5) but they're a completely different animal to all of their predecessors for a whole host of reasons. Sadly, I feel they've lost the essence of the original design along the way, IMHO.
If it's not already apparent, I'm a Stingray fanboy - in the 50 years I've been playing I've owned 18 Stingrays, a Sabre, a Bongo, and a USA Sterling. Yes, I have a list, but oddly enough, I don't currently own one.
But to stop hijacking the thread and get back to the question posed by the OP, 'regular' USA Stingray 1200 and up, Special/Classic 1800 and up, pre-EB think of a number and double it! Good luck with your sale/hunt, @Supernaut.
