Agree there. The S series have more rounded edges and look less mean than even RGs imo.
I dont like the rap Ibanez gets for doing only metal, two of the longest supporters of Ibanez today are George Benson and Pat Metheny, neither of which are metal.
I think the visual of many a Scandinavian metal band, who the kids here in the states worship, is a big part of the Ibanez legacy. While George and Pat use Ibanez the fans are less influenced by that. They look like other jazz guitars but something about the RG shape and its long history with all types of metal, plus that Ibanez logo, are forever cemented into the history that is metal. I think the only other logo as iconic in modern metal is the Marshall logo. I don't know why modern metal guys simply don't don brown SGs (like Angus Young) or Charvels as much. Ibanez almost has a corner on the modern metal scene, especially with 7s, 8s, and the popular Wizard neck. I don't think Ibanez (or Schechter or Jackson) will easily shake the "metal-only" moniker. Gretsch is stuck with rockabilly but can do so much more, and Rickenbacker is a retro or alternative guitar that can also do so much more.
Back in the '80s and early 90s it was even more pronounced. You had your Joe and Steve, but then there was Vinny Moore, Paul Gilbert, Reb Beach, Phil Collen, Alex Skolnick, and others. If it wasn't Jackson/Charvel then, it was Ibanez when we were talking about shredder metal. The guitar magazines on the newsstand was the way to see what was going on, since there was no internet, and besides all the articles with the metalhead guitarists who played Ibanez, the company littered every publication with ads pushing the metal models much more than the Bensons or some Ibanez Artist used by a non-metal artist. A big part of cornering metal (with Jackson/Charvel) was by design. Ibanez knew what they were doing but hurt themselves in the long run with legions of non–lead centered guitarists who went the safe route with Fender and Gibson.
