I saw Joe play in London this year and the sound was fine.
He had the fretless guy on before him at that gig. I thought he was OK, he was definitely different. The audience gave him a hard time really, It can't be easy opening for Joe Satriani whoever you are.
Talking about sound levels, I saw Gary Moore a couple of days ago and that was way too loud for comfort considering it was a 3 piece band playing a blues set.
I only went out of curiosity and it was local. I wasn't a fan before I went and I'm still not a fan now, that was an embarrassingly dissapointing gig!
He can't become a blues player after years of hard rock playing, and expect his fans to just go with it, without seeing some fireworks in the set.
You don't become a blues player, blues players just are!!!!!!!!
