My local club is the one venue where almost every band praises the sound.
 
	 
 
	It is rectangular with all dimensions very different. The ceiling steps down at the far end, but is all suspended tiles that absorb sound well. This mesms there are no strong resonances.
 
	 
 
	One side has several windows, but with curtains. Curtains across the patio-style door behind the band. The ends of (normally hidden) skittle runs each side create modest sound traps behind the band. The suspended floor gas heavyweight vinyl that seems to stop any booming. It sounds fairly dead with no noticeable reverb.
 
	 
 
	Asudd from the curtains, none of this was deliberate, just a happy chance.
