Just the old Radio Shack cheapie special. All I remember, it had A and C weighting (A for Annoying ) and a sort of averaging function. Bands I worked for often exceeded 110 dB. Even with the PA off! Rooms generally were so small, there was not much point in trying to position beyond the "critical distance." Audience was in the room, with the band, and might as well have been on stage because the echo in the room kept the volume up even if you tried to move away.
