Took on an average guitar player a year ago for Band A. He responded to an ad I posted asking for a person who will not only play guitar, but also book gigs. He didn't book gigs as promised, but focused on the music and steadily improved to be one of the better guys in Band A. Even fought me when I raised concerns about his lack of gig booking as agreed. I kept the band working, and then formed a trio version of Band B with him for lower paying gigs. I booked 90% of all gigs while he continued to focus on the music. I also found a killer drummer for Band B who I really like playing with. I also kept this guitar player working and busy a lot of nights per month when he faced a period of unemployment. But by the way, I hate booking gigs, and although people think I'm good with promotion, I would rather the burden of promotion and booking was spread around -- that was why I brought him on to share that with me -- and he agreed. Last night on the phone he tells me he thinks I should move over to doing promotion only in Band B (encouraing me to voluntarily leave Band B that I initiated, found a drummer for -- and replace me with some other bass player -- while we both continue playing in Band A together). Apparently, he's not happy with my musicianship in Band B, althoug he didn't outright say it. I find it hard to believe that he would even suggest such a thing since he hasn't pulled his weight in the promotion and booking department as promised, so I have had to do it, while my own playing suffers. That he would think I would would agree to a demotion to lackey status in the band B I started while he and some other bass player and the existing drummer reap all the rewards -- makes me think this guitar player has a screw loose. I think I should fire him from Band A AND Band B given his ungrateful attitude, and his outrageous suggestion that I voluntarily quit the band B. Our drummer in Band B doesn't think I should move off the bass chair, which is a vote of confidence, but the tension this has created makes me want to see the back of him, even if he is a good player now. Comments -- what would you do? Based on his behavior here (which I consider deeply ungrateful and insulting) -- Fire him and find a new guitar player? Or some other approach?
