Re: jammed on an rg927 today...
The 920/921s have necks that are quite a bit more substantial than a wizard. It is my new favorite.
My 921 was visually perfect except for a small white dot near the tuners. The nut was screwed and the 22 and 23rd frets weren't fully seated on the bass side.
a half hour of work ( had to radius and lower the nut, wack the frets down with a block of wood and hammer) and it is one sweet playing guitar.
Easily the equal of my carvin and my warmoth ( pro setup). It is light years better than my made in japan rg520qs ever was. Even when it was new.
i was impressed to say the least. Mine was a factory 2nd too.
