After complaints of us being too loud from neighbour's, we now use an electronic drum kit with one of my bands. We put all the instruments (via electronic drums, 2 electric guitar amps, and my bass amp) into a 8 track vocal mixer, and then put the output into the drummer's stereo speakers. We can then play at ridiculously quiet volumes, no louder than it would be if you were playing the songs off a CD. The noises made by the drummer hiting the electronic drum pads are too quiet to worry about.
