Don't know if it's 'typical' for us mere mortals, but John Entwistle's live work with The Who when he was playing Alembics is just a savage tone; I often think of the live 'Won't Get Fooled Again' from the 'Kids Are Alright' movie, it sounds like like, hell it's hard to say, but almost like a clavinet on steroids, but that was his tone. Geez, that would have cut through anything.
For me, it's hard to pick out one axe from another on recordings. At least on the latter-day James Taylor stuff, you can hear Jimmy Johnson on his Series axes, probably the most accessible of any Alembic recordings. Not to mention his work is an utter primer for taste, pocket, and tone. JJ's work on more frenetic music (his outings with Holdsworth, for instance) are jaw-dropping, but it's just over my head. The JT stuff I can actually understand, and it's wonderful to hear him at work, and speaks to an amazing versatility that's he's just at home with either.
