I had the good fortune to watch Steve in action recording my friends Oxbow in SF back in the mid 90's at Coast (AKA Toast), and Brilliant studios. Here's a few memories:
There was a pool table in the basement rec room at Brilliant, and Steve had a standing offer that if anyone could beat him at pool, the day's session was on him. We all tried, but nobody could beat him.
He spent a very long time carefully setting up the guitar mics- IIRC he used 3 mics on the one Marshall cabinet, one close and 2 farther back, very close to the floor ( this was at Brilliant, which had a very large recording space with skylights, there was even a small tree, sadly condo'd over now ), moving them in tiny increments to get them all perfectly in phase. That was interesting, because he had a large ( HP?) oscilloscope on the console, which I believe he was using to help him with his phase alignment. When he was finally satisfied, and we listened to the playback, the guitar sound was enormous- really full and spread out.
He was a nice guy, very funny, didn't suffer fools, and said kind words about the 2 previous albums I'd done with the band. He's a big loss, and I'll miss him.
