I have a 76 MM and its a gorgeous guitar to play, however, the one pup on MM's can be limiting.
You'll get great funky tones and aplenty of Fender twang, it will also encourage you to use your volume/tone controls more to find different sounds. Something a lot of guitarists dont do.
There is the option of mods but it will lower the value in the case of a resale. My MM has a SD Hotrail fitted in the bridge position;

I would trade fo sure if you like how it plays. 😉
