It's all about TONE ! I saw The Martin Barre Band in a 800 seat venue . He had a Soldano head and a SINGLE Barefaced 12" cabinet . The sound was excellent . The board was fairly compact . I am sure THEIR sound engineer was totally in control and no one was killed with stage volume . Previously he would use a 2-12" Marshall cabinet . I have seen Santana with a small Mesa Boogie set up in a stadium . Let the sound engineer work the house sound .
He does (to a certain extent). If you look closely, only two speakers are mic'd. When I saw him a bunch of years ago, I noted that only a couple amps had cables running to their inputs. If you watch the Rig Rundown, when they show the back of the wall, only a couple cabinets are connected. It's pretty funny! Beyond that, as one who was a teenager in the '70s, I still get excited when I see a huge backline despite knowing (or suspecting) that most of it isn't running anyway.
Makes Marshall look useless, all those Amps (28) and Cabs (12) and all the Bass Player needs is one Head and a 8x10 cabinet. Drummer, just two sticks and a block of wood.
A wall of fake Amps and 4x12-cabinets. Left to the stage a single Ampeg-Refrigerator…like this would fit the bill to not faked Cabinets of the guitar….other than that, outstanding Band!
I think that they're all real. Most of them aren't one or connected. Watch his rig rundown on RU-vid...when they go around back, you'll see that most of the amps and cabs aren't connected. It's funny!
