My GH2 360 X-Plorer does not work with GH3 very well at all, infact it's near unplayable. If you only strum one direction then it works fairly competently, yet if you double strum up and down 1/5 times it won't register. Very, very annoying. Looks like i'll have to spend another £30 on the Les Paul version (which I read has plenty of it's own share of problems).
