I'll be rehearsing with a 4 piece this afternoon in the drummer's garage. Bass, guitar and keys go through amps but turned well down, vocals are unamplified, and the drummer uses an electronic kit. It's a very pleasant volume, and one of the few times I play without earplugs.
On the other hand, I'll be rehearsing with another 4 piece on Thursday evening in the harmonica player's house, different group of people, we rehearse at gig level, with a hard hitting drummer. No idea how we get away with it in a residential area, but we've been playing there every week for four years!
