Preamp compatibility for a musicman Sabre restoration
So I got an 85 Sabre recently but some doofus switched out the preamp for some “faithful to 76” aftermarket thing for some reason. I’m wondering what will be compatible with the Sabre? I heard that a Sabre of that year can basically be compatible with almost any Ernie ball 2eq preamp, I just have to run the pickups through a toggle switch and hook them up to the right control plate(something I can have an artist friend craft from scratch). Is this true? Will hooking it up to for example a 3eq or a pre Ernie ball 2eq hurt it? Would it be able to run off of any old stingray eq set?
