OK, last post before I exit this discussion.
I spent 16 hours at the show this weekend, in two chunks of 8 uninterrupted hours.
I didn't set foot out of the venue. I didn't wear earplugs. I'm not deaf now, nor was I before yesterday. But I didn't find the noise impossible to live with, I didn't get bored, I met one of my bass idols (David Ellefson) and got his signature for Basschat, I could have attended other awesome masterclasses and gigs if I had chosen to, I gassed and drooled over fantastic equipment, I spoke to a lot of friendly people at the stands - as well as to a lot of Basschatters... and all that I had to endure was a bit of a headache last night, which could have been caused as much by my continuing cold as by the slapping noise.
Remember that bad publicity, appropriate or unfair, on this site or anywhere else, may lead to dwindling attendance and cancellation of the show in the near future. When that happens, don't come complaining that you can't see decent basses or gear in the shops anymore and you have to order blind online.
