I compare the Front & Center mic, 1959 Shure 440SL mic, and Shure SM57 mic with Bulletizer from Greg Heumann at www.blowsmeaway.com.
Whadda ya think?
TEST NOTES: The Shure 440SL mic is louder than the other two... a LOT louder. The amp volume was on 5 (out of 12) for all three mics, but I had to turn the mic volume way down on the 440 to get the same perceived loudness on the amp.
