I've been paid as little as a copy of the cd for loaning instruments for others to play, mandolin and autoharp specifically, because the musicians didn't have their own. (Was stiffed once by an artist who I'd rather not be known for playing with anyway.) Usually I get paid in cash what I negotiate, a copy of the product, and future considerations. Years ago one small market gospel release with a very kind and generous thank you in the liner notes got me enough referrals to make it worth my while.

For shared projects, ie where I actually have artistic input and decisions (writing, arranging, production) or am a band member, I get a percentage of the profits. With one duo I'm in, the other guy gets a bit more than me because he provides the recording gear and looks after most of the business details, but even then I get about 40%.

The exception is when I play as a favour for friends.

For complete strangers, depending on time, expenses and travel, anywhere from $100 to $200 per day up.

For what it's worth.

Peace, Mooh.
