If gnat's wotsits are a measure of audible difference, then I can hear a tiny bit of each. There was a noticeable difference in the way the bloke attacks some of the notes, especially in those 'slap-fest' bits, which affects the auditive result. They all sounded like good instruments, but how much, if any, of the gnat's wotsits difference is down to the wood essences used, I'd say the jury is still out. Inconclusive, bordering on proving the opposite, to me.
(I won't be hiring the player for the stuff I like, either, but that's neither here nor there...).
