Bah...Vail's probably the most professional bassist in the most professional show I might have ever seen. He just has strong opinions and says them. I got no problem with that as long as he stays off my beloved Ampeg!Jimmy, with all respect...the tone of the conversation isn't what I'd expect from a seasoned veteran. It has all of the vibe of the people who start threads in basses to dump on ERB players, etc.
I also have to wonder, out of all those millions of gigs that Vail is happy to tell us about all over the planet (you know, with every amp that's ever been made)...how many of them is he unloading the truck personally. The weight of your gear becomes a lot less important when you're not doing the moving yourself all the time.
Sorry, but a big part of "professional" is about comportment.
And just because you're famous and play with big-time folks doesn't mean you don't have to sling amps sometimes. I play with bigtime folks and a lot of times I don't have to touch an amp, but I still have to move them when I play locally. Not all of us can hire cartage to go play a local gig
