Seeing this is recorded to be an advertisement for his educational course maybe consider that the signal is heavily processed at the desk (or post-production in the box). As far as I can tell there's an octaver in the signal, a direct in to the desk and a mic in front of the cab.
Just going 'ah, flats!' While stroking your chin, taking a puff on the old pipe and staring into the middle distance really doesn't do the process justice.
