I have this RG350 with a maple neck/board and black sharktooth inlay, which I actually only bought because of the maple board.
But for some reason I thought it sounded "muffed", so I replaced the stock INF pickups with a Dimarzio Norton and a PAF Pro.
The result was that it sounded much better, but still not to my liking, so the guitar was put in the corner, drop tuned it for occasions. Then I took the pick-ups out for a RG548 and it was never played again.
Then I could get a transparent blue swamp ash body, from what was originaly a RG547 (I think).
Bought it, put the maple neck on it, a black pickguard from my RG550 installed the QM1 and QM2 pickups that were originally in my RG620.
Also installed a kill-switch (just for fun) and an Edge Pro trem.
Now I have a guitar that will be played! realy like it! All the "muff" has been gone, and for now I like the QM pickups in it.
