	I'm not a neurologist, but I could hazard a guess. Depending on 
how, er, well-covered one is, if you hold up your forearm before you,
and flex each finger in turn while looking at your arm, you'll see that 
you can observe the tendons and muscles flexing, maybe even all the way 
down to your elbow. I'd guess that a suitably-arranged pressure sensor 
could thus feed back to the amp details of which muscles were working 
when. Though how it can tell whether you'd have fretted an invisible 
guitar properly or exactly where those fingers were to be placed... 
smoke and mirrors I reckon :-) Yours,
				      Jon (whose ears are still buzzing 
from Motorhead last night--review to follow)
