Right i've recently started developing my lead playing so im in the upper registers a little more and the dodgy action on my RGA is doing my head in.
It's nice and low down the bottom end of the neck but at the 12th fret its something like 3mm.
If my thinking is correct a shim in the back of the neck pocket could rectify this a little?
The neck is pretty much straight currently.
Any advice is greatly appreciated.
I might just send it off to Legra once i get my other guitar back as the frets could do with a bit of work too and the nut could do with being replaced.
Is the bridge adjusted correctly? The only reason you should have to shim the neck is if the action is still too high with the bridge set as low as it will go. Ibanez is usually pretty good about that kind of thing.
Keep in mind that when you set the bridge really low, you'll have to be much more conscientious about the amount of relief in the neck. Too much relief, and the upper frets will buzz. Too little relief, and the lowest frets won't sound at all. You can't actually do a perfectly flat relief, but you can get away with less relief than people commonly use.
