Mid 70s "Lawsuit" Ibanezes are still collectors items. In the 70s Ibanez was making copies of Fenders and Gibsons that were higher quality (a fact that "Brand Snobs" of my generation scoff at) and ended up getting sued for it. After CBS bought Fender they started doing stupid shit like 3 bolt neck joints. As for Gibson nearly everyone I've known who had played that vintage of Gibson has had to rewire it, replace pickups, and do something so that it would stay in tune (either change tuners, or pull a Steve Stevens and put a Floyd Rose locking nut on it.
