The guitars I know that either have the same neck or similar neck and 2 hum configuration would be the JCRG-3, RG8520 (pre-2004), RG1802, USRG30, and a very small number of UCEW1FM's. You can go to
www.ibanezregister.com and check out photos of all of the guitars I mentioned as well as ones that you might think it is, I am sure you will be able to identify what you were thinking of there.
