He already has.
I'm sure seem to be the oddball on this one, or at least in the minority, so take my thoughts with a grain of salt as needed, but...
I had a KILLER alder/Brazilian NYC PJ5, and while I really did like it a lot, it just didn't have quite enough edge for me (I know, I know, that's not what most P or PJ players are focused on). I played the ash/maple PJ5 and boom. There was MY PJ5 tone. I love that bass. The alder/Brazilian I had was much warmer sounding... definitely more of a classic sound to it (if you can even say that when referring to a PJ anyway). I guess I'm just too much of an ash/maple fan in general. All three of my Sadowsky basses are ash/maple. I know, boring, but I guess at least I know what I like, right?
