I agree with the suggestions regarding talking to him to see if you can work something out on a schedule. Keep in mind that this guy pays for the house that he lives in and your sound is invading his space. Most of the time, I've found it's not the guitar, vocals, or drums, but the bass. 
Every time I've gotten a complaint in a sound reinforced room, it has been the bass.
Maybe thin up your tone and add something else like distortion for the fullness that your losing. Then at the gig, crank it up!
Compromise is the best thing I could suggest. Let him know the steps you are taking to work with his concerns.
