I'm torn on this. On the one hand, like everybody else, I'd love to see Ibanez open up a Jackson- or ESP-style custom shop where you can just call them up and list what you want ("Powder Cosmo Lo-Pro, JPM electronics, through-neck, ebony fretboard, Hello Kitty inlays" ), but that seems about as likely as a 2001 mecca777 signature model. This is, after all, Ibanez we're talking about.
At the same time, I'm not sure that I'd use that service, because I would mainly be paying to have "Ibanez" on the notched-pointy headstock. Personally speaking, if I was thinking of spending several thousand pounds on a new guitar, built exactly the way I wanted it, I think that I'd probably just call up a UK custom builder, and spend 100% of the money on the guitar, instead of shipping, import duty, VAT, Ibanez logo and the rest.
Still, I'd love to see a return to the limited-option days of the early 90s, with some high-quality J-Custom or Prestige models that could be lightly customised from a range of different options, priced in the same range as the current high-end Ibanez instruments.
