Introduction
In my original post, I'd identified this beautiful guitar as an AR300, as the top looked like curly maple to these untrained eyes. However, Wojtek Kalinowski has pointed out that the top is actually Burl Mahogany, as the 'wood grain is short and is facing 'north' (headstock).' Therefore, this guitar is actually an AR305AV. Many thanks to Wojtek for setting the record straight.

Oct 15, 2014  I just bought a new Ibanez AM93 semi hollow with Super 58 pups. Firedtv drivers. I checked with Ibanez and the dude said they have Alnico 5 magnets. I am a Duncan Alnico II Pro pup freak and I have them in my Midtown, Fret King Elise semi, and Tele due to being a blues and classic R&B player, lots of big 6 string chords rhythm through Deluxe Reverb with big Weber Alnico speaker.

The Ibanez 'Tri-Sound Coil Selector System' enables each humbucker to function in either humbucking, single coil, or parallel coil mode. When combined with the 3-Way Toggle Switch, this system is capable of producing '15 distinct sounds.'
The 3-Way Toggle Switch, Control Cavity and Output Jack are shielded from 'induced hum' by 'chrome-plated metal shielding' containers. These containers also ensure the 'proper grounding of all electrical components.'
