I've played in plenty of situations where there was a house PA, some where there was only a vocal PA, some where we had our own PA, etc. In my most recent gigging bands (all-original rock bands
Link Removed,
Link Removed, and
Link Removed), we have stumbled upon the best possible scenario (IMO):
Tell the club owner that rather than paying you to play, they are just in charge of paying for the sound guy (which you should already have lined up as a steady soundguy) AND an ad for the show on the radio (if they don't already do this). Then tell them you'll play for the door (just pay someone you trust $20 to run the door). Set the cover around $5 or so. This way:
1. The club owner gets off only paying about $400 or so, which is very reasonable, considering they might normally have to pay out $450 or more for a cover band.
2. The sound guy gets paid guaranteed, regardless of the unexpected "slow night".
3. You don't have to worry about haggling the price from the club, and you don't have to worry about paying the sound guy, because these are already worked out (LESS HEADACHES!

4. This gives you a major incentive to get off your butt and PROMOTE your show, as you get paid based on the amount of people show up and pay the cover!
5. Club owners will absolutely LOVE YOU if you bring a huge crowd, as their beer sales will be through the roof, and will probably be willing to give you a little something extra as a tip. (Once we brought a great crowd and the club was so impressed that they gave us an extra $200)
With a good crowd, you're able to pay any openers you have, even if they don't expect to get paid. Also, you don't have to worry about getting a PA, a van, loading in/out, setting up, and running your own sound (Again, less headaches).
The club owner is happy because of low cost and no b.s. The sound guy is happy because he gets paid guaranteed, and can count on your band as good steady work. Your openers are happy to open for a good, professional band, and in many cases they're ecstatic to get paid. You and your bandmates are happy because you have very few responsibilities or b.s. to deal with other than loading in your amps/instruments and actually PLAYING. Also, you will make out alright in the financial end of things, which makes everyone happy. AND if you have an opener or openers, you might only have to play a couple hours, which is awesome.
Sorry for rambling, this is just a method I feel very strongly about and highly recommend. There is no arguing over a jointly-owned PA, no arguing with club owners, no problems with soundguys, no b.s. whatsoever. And
I've never run into a soundguy, club owner, opening band, or bandmate who had a single gripe about this system. Has anyone else done this?
