Since the lockdowns, my gigs have paid between £0 (charity gig after the death of a good friend) and £200. The average is between £80 and £100. The bands I'm in are good and I'm also connected to many guys who put dep gigs my way.
I look at gigs as being better than sitting at home. Every one is an opportunity. They get me seen and making contacts. None of the guys I work with go out for peanuts, so if I like the band I usually don't even ask what the fee is. I wouldn't leave over money, unless the bandleader was ripping us off!
