In no particular order:
- being the only one in the band that knows how to setup the P.A.
- having the heaviest equipment.
- placing a bottle of beer on my amp only to find that it vibrated off during the song.
- 90% of all bass solos, especially if it is an interpretation of Hendrix's version of The Star Spangled Banner.
- audible tuning
- double bass pedals - rarely necessary.
- guitarists that don't, can't or won't play "the hook" of a song.
- drummers oblivious to the idea of playing WITH the bassist as part of the rhythm section.
- being the only one in the band that plays on every song, nearly all the way thru each - (sometimes I can't take a drink or wipe the sweat off my face for 3-4 songs).
- guitarists that think they can play bass (some can, most cannot).
- singers that don't do anything (sometimes I ask the singer to "move this over there", then ask him three minutes later to move it back - not because it needs to be moved, but because he needs to do SOMETHING!)
- drummers with no sense of dynamics.
- drummers overcompensating with large drum kits (few can effectively use more than a 4 piece).
- musicians who fail to understand that in most cases (i.e. with FOH PA and limited stage mixes), their amp is for stage volume - in other words turn the %^&* thing towards the rest of the band so we can hear you - it doesn't have to face the audience directly.
- anyone who consistently borrows 9v battteries.
- when the sound guy is nothing more than a glorified dj. (I really don't mind a-hole sound guys - I just want them to be good at what they do.)
- lying club owners/managers. "you guys only brought in 75 people tonight"
- people getting onstage when we are performing. (old guys: think Pete Townsend and Abby Hoffman)
- band members that never have this month's (or last month's) rent for the rehearsal space.
- bassists with an inferiority complex.
