Thanks for the responses. It's a 4 piece band with a sequencer. We have a decent PA and gear it's more an issue of the mains than monitors we're all IEM and those are mostly dialed in and it's just minor tweaks as we go.
It's tweaking the EQ and settings between an outdoor patio gig and an indoor gig in a small brick and tile square room which can make the system sound and respond totally different.
My requests to leave and get setup earlier so we're not rushing to setup and soundcheck with people there is falling on deaf ears and I'm slightly frustrated.
It sounds like your band and mine have similar set-ups (my band being 5-piece but no sequencers)... and similar priority issues. We run all our own sound and I would say that we wind up doing a full-band soundcheck no more than 1 out of every 5 gigs. For better or worse, our BL is really big on lights and we have a pretty comprehensive light show (which we also set up and run ourselves), so by the time the lights are all up and running there's usually not a lot of time or energy left for a traditional soundcheck.
What usually happens is a full soundcheck on the drums (10 minutes max), then a brief run-through with just the drums and bass (5 minutes on average, never more than 10), and then all the other instruments and vox get a line check and that's it. And sometimes I have to push to even get a bass soundcheck with the drums... it's just not that important to the BL and the other members.
What really saves our bacon is digital technology and in-ear monitors. We use a Yamaha digital board with saved mixes for the various types of venues we play (small room, big room, outdoor, etc.) so even on the numerous gigs we go live without a full band check our sound is still reasonably dialed-in from the first note. Also, the amp I use (a Line6 LowDown 150) is DI'd to the board and has pre-sets for both of my basses, so a consistent sound in tone and level is hitting the board every time. In fact, even my stage volume (Master) never varies by more than about 15% regardless of the stage. And finally, we are all on wireless IEMs and those IEM mixes are also saved in the board. So as long as everyone's belt packs and earbuds are working, we're pretty much golden.
So bottom line, the 20-25 minutes we average on a soundcheck is certainly less than ideal ... but thanks to modern technology it's not a gig-breaker either. We almost never get a complaint about our sound and in fact we are complimented on it quite a bit.
