Gut feelings can be tricky. While I'm a proponent of trusting one's intuition, it can often be difficult to know what, exactly, those feelings are trying to tell you. Sometimes it's not what you think, and the feeling turns out to be about something else. Certainly, I don't think it's necessarily a waste of time to play with less experienced musicians, but as to whether it will be a rewarding experience for you, only you can decide that. Bad feelings aside, I think the campsite rule applies in most situations: always leave it better than you found it. So if you do end up playing with these guys for a while, stay open to new ideas, share your knowledge, have fun, and enjoy. You might find it more rewarding than you anticipate. Tom's Ramone's story is a good case in point. Those guys may only have had three notes in a bassline, but wow, how those lines were delivered! Also, having a more experienced player in a band can raise everyone's abilities to a new level. As posted in another thread here recently, it's amazing how quickly people can learn when they're ready. Way back when I was an actor, I found that the really top artists were the ones who made even the most inexperienced novice look brilliant. That was a truly humbling and amazing lesson to learn. Just a thought. Still, you've got to do what works for you. I'll be curious to hear what you decide!
