I bought a JTV-89 hardtail when they came out almost a decade ago. I really like the sound of the "real" bridge pickup. Have they kept building these with the same pickups throughout the years? I bought some from a guy that had replaced his in his JTV-89F, and am going to install them in another guitar, but want to make sure it's the same thing before I go through the trouble. I probably should have asked before I bought the pickups.
