there are SO many variables her .how big is the club ,how many people are in it .What i know from 1/2 stacks is they are very directional .the girl dressed like Brittney at the 4 th table to the left will be half deaf .they rest of the club will hear mud .When you mic an amp whether it is a 212 combo or a 6 foot stack the difference will not be noticeable to the people in the room .Unmiced YES ...but i dont know a lot of bands that run umiced . again cool factor ..sure more metal yes ..but more effective than a 112 other than looks ..not nescessarily
