Finally got around to actually watching the video... Yeah, the tuner did seem a bit extreme.
But then again, this is obviously a bunch of really big audio nerds! The specs, acronyms, protocols and buzz words used during this video was kind of crazy.
I think its kind of a "we are going to do it like this, simply because we can" type of situation, with running everything digital, having this crazy modded pedal built to allow keeping things 100% digital et al., again simply because they can....
I think that is kind of rock star excess to a pro audio nerd.... Some guys would be all about hookers and blow, green M&M's, white tigers and such; other guys use fortune and fame to have the only 2 digital digital tone generator Boss tuner pedals in existence created
More power to them though.... what fun it must be to work for a boss/tour that basically says money is no object, make it as good as you possibility can, I don't care how diminishing the return, do anything you'd like to try.
There is a certain enjoyment in doing something to the highest possible level possible, regardless of the need. My last road bicycle I built for example, I used carbon fiber everything, ceramic bearings, all electronic shifting, all hidden electrical connectors, every part designed to be as aerodynamic as possible etc etc, and yet I never will ride at a performance level anywhere near actually noticing any real gains from those parts. It was simply a "because I can" type of project and it was lots of fun.
Home HiFI sytems, muscle cars, guitar rigs... and in this case touring sound... boys like their toys
