I won't consider a guy who can't play bass in the first place, so the number one thing I look for is someone who won't waste my time.
- Show up to rehearsal prepared with the material already learned.
- Answer e-mails and phone calls promptly
- Keep your commitments for gigs, rehearsals, and other band activities
- Be able to give an answer to whether you can rehearse, or make a gig in a timely manner.
- Get along with other band members and know your role in the song, and in the band.
- Help out with things other than just playing bass, such as promotion or setting up the PA.
- Bring as much of your own stuff as you can, without having to borrow from the band. That includes stuff like mic stands, charts, music stands, cables, etc.
- Have your own reliable transportation.
In short, being able to do your job without requiring a babysitter.
Yeah that about covers it. As bad as it sounds to say, a lot of bands just want to be able to "set it and forget it" when it comes to the bass player. The band I'm in now, their lead singer and lead guitarist were splitting time on bass and the first thing they told me in the interview was, "we're hiring you cause we don't want to worry about the bass anymore." Now granted they already knew I could play, and I had worked with the lead guitarist in other projects so he could vouch for me both musically and personally, but it still surprised me how UN-important they considered my gear, influences, soloing ability, etc.
Many times a band already has plenty of volatile personalities / big egos and they're not looking to take on another one, no matter how talented you may be on your instrument. Or as it is often referred to, the "hang factor". In my market if you can play reasonably well, you have a sense of personal responsibility, you've got decent sounding, RELIABLE gear and your own transporation, you'd probably be considered a godsend to 80% of the bands around here. If you can double on upright and/or sing, your value goes up even more.
