I was trying to return a defective sm58 to the 'Pro Audio' dept at Guitar Center the other day...here's the conversation:
me- This thing isn't working. Gain cranked, no signal.
sales genius- Oh, sometimes these need a little phantom power for that "extra boost."
me- No, it's a dynamic microphone. They don't require phantom power.
sales genius- Oh yeah I know, but uhhm, sometimes the phantom power will really boost the signal.
