Interesting he talks about one of his rigs is a triple rec which he really likes.

Boston Is Back: Tom Scholz Talks Tone | GuitarPlayer

I switch between three main recording rigs. I still have the ’70s Marshall head I’ve used from the beginning—which, as always, I run with equalization, gain, and compression ahead of the amp, and an [SR&D] Power Soak after the amp and before the speaker cabinet. I run miked signal from the speaker into an EQ with narrow bands that let me select the frequencies I want to emphasize. That’s the sort of sound I designed into the Rockman stuff, which makes up the second of my three studio rigs. The third setup is built around a Mesa/Boogie Triple Rectifier head that I really like.
