It's probably more a matter of supply and demand. Ibanez keeps a number of through-necks in their line up and reduces and increases them every so often, but they always are in lower numbers compared to the bolt ons. Given that Ibanez is one of the most successful guitar brands in the world, one has to rationalise that they're doing something right and know their market.
In other words, not enough people want an Ibanez through-neck for them to warrant a huge range of them.
But then you also should be asking, how often does the sort of music that most RGs are used for even need limitless natural sustain under low gain conditions?
I've never had sustain issues from any of my Ibanez bolt ons, to the point I worry about the construction hampering the sustain. Most of the time on an Ibanez folks are trying to get as many notes into as shot a time as possible, not get one note to hang on bar after bar...
Besides the MTM2, I don't see any necktrough on their current line. I'm not saying they should offer all sorts of neck trough, but just some options. LTD/ESP has a couples of necktrough on their line, I asume it's because they sell some!
I do understand that for shredders that plays the most scales in the less time they can, sustain and tone isn't realy their "cup of thea", but many of the artists and buyers of ibanez's are not only shredders, you got plenty of metal and metal-core who are kinda trying to get the best tone they can, and chugging is as much as part of playing as "shreding up the neck" is.
I was just wondering if anyone knew a specific reason why Ibanez doesn't offer it more ofter
I know it's realy specific, but once you get a taste of a neck trough with Mahogany, it's kinda something you 'd like to have on your next purchase! It's just kinda blows that I'll most likely have to browse the classified instead of my local reseller!
