It's been suggested that it is a blackface, but due to the older style knobs and logo plate, it looks to me like possibly a brown '62 or '63 that has been reupholstered in the blackface tolex and grillcloth?? Or maybe a BF with older knobs and logo?
Here he is with a Travis Bean TB2000 bass (11/26/77)

Here it does kinda look like a blackface Fender (11/23/83)

(4/23/79) Notice there is a Mesa combo on each side of the stage; a guitar extension for Merl's side? ... RIP, Ron Stallings(center) 1947-2009

I'm digging up my own old thread because I found it on Google search.
I've never forgotten this great post but wasn't really ready to absorb it, and I'm still not except in a very long-term-planning kind of way.
I know diddly-squat about Fender amps other than all you Jerry guys use Twin Reverb preamps. I understand that the Alembic F2B is based on the Dual Showman preamp. But the preamps were all pretty similar, right?
The Fender head on top of the Mac in the picture looks to be far too small to have much of a poweramp section inside... but I've never heard of Fender making a separate preamp...
