I’ve been in the house band for a Sunday jam for over twenty five years now in my favourite blues dive downtown. I let people use my gear and have never suffered any incidents. Some nights I’ll do the entire night , but most nights have some friends sitting in. Someone said that on a good Sunday night you have both extremes. There’s a little misery , and some great playing. All levels , all ages. It can be my most enjoyable night of the week. Whenever I get tossed something I’ve never played I do make note and learn the parts later. As long as somebody knows the tune we’re generally on.
It is surprising to note how several players using the same gear , same settings , will all sound very different.
