If Gibson can get away with suing Ibanez (and in the process halting the production of some of the most amazing electric guitars ever produced), then they can get away with anything.

Everyone in their time should try to find an Ibanez GR520. A Ghostrider. These things play like the best Gibson Les Paul you could find... Except they sound better (thank you Dimarzio PAF), the craftmanship is just as good, they're LIGHTER (a lot lighter), and the hardware is just as good. But Ibanez doesn't make these anymore (I'm assuming because of pressure from Gibson).
