When you say that you want to change the sound of the bass, how fundamentally do you want to change it? I suppose that different people have a different idea of what is the defining characteristic if the Stingray tone , but for me it is that springy, zingy upper -mid / lower treble coupled with a very noticable scoop in some of the low mids. Add in the big bottom and slicing treble available and you've got the sound of a Stingray. Musicman Stingrays have got a very peculiar frequency response ; that's why they sound a bit wierd compared to most other basses . Adding an East preamp ( be my guest) may offer some extra tone shaping options or a slightly different flavour to the sound, but my bet is that it will still leave your bass sounding like a Stingray. If you want your bass to sound like another type of bass i.e a Fender or Warwick or a Ken Smith then I fear that you will be dissappointed.

This.
Once a Stingray. Always a Stingray. You can dress it up with off the shelf electronics but the pickup type, position and construction means it's always going to be fundamentally Stingray. If you don't like that sound, then the Stingray is not for you. Modding is an option, like stated above - like putting in a P bass... but then you are in dodgy ground - butchering an instrument... and then it may not even give you what you want!
