I only agreed to the studio time because from what I was told, the studio could work with my schedule. The guitarist found out the first day he went in that that would not be possible.
Sounds like you were mislead. Important detail. That puts some of the responsibility on your band mates' shoulders.
If I made it clear that I could not take time off and could lose my job for doing so, and my band mate told me the studio would work around my schedule, I would expect that to be the case.
It really changes everything in my mind. Keep trying diplomacy. You say they are friends, I hope they do the right thing.
BTW, some of the people sharing their legal advice on this thread obviously have no idea how a small claim works.
