lol yes they would!
Well what happened is I was at a musicians flea market, and they had a smaller room in which non-dealers could sell stuff. One guy had a bunch of old Marshalls, a 1971 1959SLP, a JTM45 which I would have bought if I had known I could sell it to the smithsonian for a brand new vette, and the Major... the first one I want to check out was the 1959SLP, but he had no guitars or cables.
So we decided that I would find the guitar and he would find the cables, so I asked some guy if I could borrow his Les Paul to try out one of the marshall half stacks. He said "only if you turn it up, all the way." Meanwhile the guy selling the amps had already crosslinked the channels, turned them both to 10 and was just waiting for a guitar to plug in before flipping the standby switch. I told the guy "okay" kind of sarcastically, and plug it in and turn it on. It was really loud... then I tap the pickup selector switch and it turns out there was a short in the guitar because it just got about ten times louder.
When I give the guy the guitar back, he said "that was the coolest thing I have ever seen in my life! I didn't think you'd actually do it!"
He also had the Major which I really didn't know what it is, but I figured it's both more unique and that it would be more of a collectable and I figured that I could probably sell it for a 50 or 100 watt head from the era. When I was walking out, some guy takes a look at that and says "nice Marshall! I'm here just to see if I can find a Marshall Major."
I paid $800 for the head and $700 for both cabinets.
