I have a similar problem. I cleared up some space for an acoustic drum kit, but I have yet to buy one due to volume issues. The drummer I know is freaking loud. So I'm still trying to figure out how to get a decent sounding acoustic set that won't get me kicked out. The drummer won't touch an electric kit.
What are the options out there for silencing/attenuating the sound of acoustic kits?
Are there any decent sounding quieter acoustic kits?
