I was kind of thinking you were going to reply with that....at 43mm it's only 0.5mm wider than the 6 string ES-1...not enough.
Although a few mm doesn't seem very much, making it 45mm or 46mm wide like a Guild 12 string would make a hell of a lot of difference in playability.
And 12 string players do spend a LOT of their time down that end of the neck....pity.
Maybe a slight modification to the current specs could be looked at?
