here is my GAX70
it's one of my favorite guitars I've ever had. well made. I really like the location of the 3way switch. the bolt-on maple neck is very sturdy. I've knocked it over or dropped it many times with naught a lick of damage. I haven't played a lot of ibanezes but I imagine this neck profile to be something of the common thin ibanez variety. I quite like it. the neck is very snuggly fitted as well, I would rate it with a good amount of sustain. the stock pickups aren't bad but you can easily replace them if they're not to your taste. it has alpha brand mini pots that work great. the 3-way switch may be worth replacing, as it's the type where if you bump it, it flicks to the center.
sublimedo has one as well. fran is a former user. dub had a GAX30 like you posted at top.
the "G" in the model number denotes ibanez's "Gio" line which is like their squier. so there are AXs as well, like the AX120 which has a dot and bound neck and the headstock looks more like a proper ibanez artist headstock. basically the AX/GAXs are like an SG version of the ibanez artist.
