I went for "a jam" with an original band that were looking for a bassist. They were pretty good, and I quite liked it, but I wanted to make it a bit more interesting. I explained that, and showed them what I meant with my chords and pedals etc. They seemed enthusiastic, kept inviting me back, charging me for the room hire, I think we did 4 or 5 "jams" and by the time I just figured I was a part of it. I never heard from them again! I texted and emailed but heard nothing until I got a random mailshot from them about a gig they were playing
The bassist they actually went with was a much better fit, and a very good player, but it was pretty annoying
