It's not just drummers, I was at my weekly 'folk jam' last night...the set-up is bass (through a 15w amp), violin, 12-string and 6-string acoustics.
The 6-string player goes straight into mad busking volume, which there's no need for in someone's living room. Thankfully the violinist is very good at moderating his volume.
Last night I did end up asking him to calm down a bit as we couldn't hear the 12-stringer.
