These are questions I've gotten from GC employees. I work for a "industry standard" mic company so keep this in mind otherwise you won't understand.
1. GC employee: This is Razor from store xyz....what mic would you recommend for a guitar cabient?
Me: Uh....
2. GC employee: How do I wirelessly connect a guitar speaker to the PA system without hearing the speaker?
Me:
3. GC employee: My customer doesn't like how long the antennas are on his "insert model for $4k wireless system." Will it still work ok if we cut the antennas in half?
Me: No
GC employee: Can I place an order for a pair of antennas?
4. GC employee: I'm looking for the invisible wireless headset.....
Me: Invisible?
GC employee: Yeah.
Me: Like you can't see it....invisible?
GC employee: Yeah.
Me: I'm pretty sure something like that doesn't exist
GC employee: I'm looking at a picture of it right here!
Me: You are looking at a picture of an invisible mic? Is it a blank sheet of paper?
GC employee: Well it's not really invisible smartass!
Me:
5. GC employee: I'm looking for an cardio headset mic for an aerobics instructor..
Me: Well zyx, and xyz are cardioid...
GC employee: No I need one that is CARDIO...ITS FOR AEROBICS!!!
6. GC employee: Do you guys make some sort of cable for your wireless mics?
Me: Like a cable to plug the receiver into your FOH board?
GC employee: No...so the singer can swing the mic around by the cable.
Me: Why not just get a wired mic?
GC employee: Why would he want that?
There are a lot more...anyone want me to continue?
