I've played in bands like this. To me it's a sign that there are non-musicians in the band. Better musicians are listening to the ensemble sound and consciously or unconsciously make choices about volume and dynamics, tone, tempo and lots of other variables so that they create a great listening and playing experience. I currently play in three different ensembles with the smallest rig I've ever owned and enjoying the music-making more than ever. Of course, the other option is to buy bigger cannons for the arms race, and when that was where I was at, I went with a great tube preamp and cheap clean power (Crown CE2000) into two SWR Goliath III 4x10s. The problem was forever solved, but we it didn't change the fact that the guitarist and drummer didn't have big ears. Charlie Haden said something to the effect that humanists make the best musicians.
