As far as the 12 string, he has never had pickups installed. He has always used mic only on those. If you'll notice when he does guest appearances and short concerts he usually doesn't pull out the 12. That would require some additional setup.

He started plugging in the 6 strings in the late 80s, early 90s. He has said in interviews that he likes a mix of pickup and mic.

One reason may be that effects are a lot easier w a pickup than w a mic. Terry used to utilize a whole rack of pedals w the acoustic. Carter uses a number if effects, but his Breedlove is a really thin sounding instrument (really wish he'd change to a Guild or a Gibson).

Just some thoughts.
