I have two opinons on this one so I'll list both.
The first is in line with Rich's ideas. I'd like Ibanez to iron out the glitches with the current regime. To me, this means the return of the locking studs.
Quite simply, Ibanez's non-endorser based reputation, in the UK at least, is founded on the fact that the Edge and Lo-Pro edge tremolo systems are the most reliable ones around. Since the locking studs have been omitted from even the top of the line guitars, the tuning stability has suffered.
As a direct result of this Ibanez have cracked the very foundation of their reputation amoungst a group of semi-professional players, who are more swayed by the supreme functionality of the instrument rather than the endorser list.
I believe a wise man once said "we are THE locking trem company". I'd now argue that Ibanez no longer stands above its peers, and that the playing field is now considerably more level.
I'd ask Ibanez to rectify this, before previously loyal customers look elsewhere.
The second angle I'd like to emphasise is as with many other folks' I'd like to see either a larger, globally available catalogue, or a Jackson USA select / Tom Anderson style semi-custom shop open. I'd envisage players being able to place orders for any of the main body shapes, RG, S, SZ etc guitars, with a choice of neck profiles, Ultra, Wizard, Viper, in a variety of woods and equally importantly finishes.
This would be a pipedream however and I doubt that it would be economically viable as past experience proves.
I'd also say get the signature models in line with the artists models. JEM7VWH with a rosewood board these days, JS1200 with an original Edge trem, K7 graphics etc. etc.
