Hello Mr. Hosono
As you probably know, many (including us here at JemSite) are rather disappointed in Ibanez's current lineup. I believe that you gain many more customers by acting upon the several recommendations/suggestions made here in these forums. Basically, I want to reiterate what everyone wishes to see in future Ibanez guitars:
1) Better Colors: The current color/finish slection is very bad. I'm not asking that you bring back neon colors (although that would be cool). All we want are some nice colors in your RG Prestige series. I would much prefer a basic red over that rather ugly pewter cubed finish.
2) Locking studs: This is a definite...EVERYONE wants
locking studs
3) The return of the Super Wizard necks: I would love to see this
4) Possibly the return of the Edge/Lo Pros? I know many here (including myself) much prefer the older Edge and Lo Pros, versus the Edge Pro.
The main two issues are the colors and locking studs though. I believe you can gain a whole new market by correcting these issues.
Thanks you for your time in reading this.
