As a certified gear geek I really enjoyed watching that video! Yeah, it was long, but it was kinda fun to see how another guy in the trenches thinks about his rig, though I have to say there's an awful lot of "Oh, you have one of those? I need one too, then!" going on in Nashville. But in my experience, it's always been that way.
As is my nature, I have a few comments...
I loved the fact that the dude puts his spare pedals and gear in a cardboard box, and shleps it around to sessions along with his uber-fancy amp head rack with the pedal drawer, his guitars (some of which are very valuable), and his custom built pedalboard. I got a chuckle out of that. I mean...he's gotta know he can get an Access-type bag for that stuff, right?! The dude has everything so organized, but in the middle of a big session he's going to rummage around looking for stuff in a cardboard box...I think he does it for the "I don't really give a damn" effect.
The ear protection product that he mentions for in-ears and headphones is such a great idea, and so small and easy to use, I can't believe I've never heard of that one before. That's on my shopping list now.
I've played Sampson-era Matchless HC30 amps, and later ones, and I can't tell the difference. Can you? I'm not sure Mark Sampson had magic hands any more than the other folks at Matchless...so I think there's a little bit of "mine's older and therefore better than what you can get now" mythology involved that so many of us fall into when it comes to this stuff. I had a Sampson-era Hot Cat 30 when he was with Bad Cat. It sounded just like the new ones do, too.
I was surprised to see a new Magnatone in his rack. I've always wondered if those were good amps. Haven't seen one locally to play through.
An old Superlead? That was cool. Got that with the HXDA in my studio, and the Tweed-ish thing is covered with the DG30. Makes perfect sense to me to have amps that do those things. I did like his road case with the drawer.
I agree with him that a buffer makes all the difference with a pedalboard, but the Boss buffers are simply not very good buffers, though obviously he is getting plenty of work and could probably care less. It just surprised me that he is so into the "special" amp thing for the small differences, but hasn't gotten into the differences between today's buffers.
Finally...standing by the cab when playing to get that effect in the pickups...I agree, and Carlos Santana has talked about it, too. The iPad remote for my DAW has made that possible now, and it seems to make me play better. And it's really because pickups are microphonic, and they do pick up something of what's coming out of those speakers.
