Numerous times.
My fave 2 examples...
One was a discussion about Jimmy Herring, and some dude arguing with me what Jimmy used on a specific album. Which I had a conversation with Jimmy about, since at the time he was the Guytron poster boy and it was as expected an old Fender and Marshall. So, the dude gets all worked up because I "claim" Jimmy didn't use his favorite. Coming at m with shit like I must have misunderstood something, blah, blah, blah. He then calls Guytron screaming about the conduct about the THD asshole o tha thread, Guytron calls my boss, Andy has to go through the thread with Guy going "well, Ed didn't say anything I have an issue with with. End result, I'm barred from saying anything about Guytron.
Case 2...
I always dug Two Rock, i some thread I said something about clonin, some 2 Rock customers gets way bend out of shape, calls Two Rock, Bill calls Andy, Andy gets to spent the aternoon reading through a 10+ page thread same end result. Ed didn't say anything wrong. Two Rock losta guy speaking highly of their amps tat day.
Suhr, Mitch from Marshall, etc, etc, been through this over and over...
The only good hing is that Andy knows I AM very opiniated and don't foget when you cut me, so as far as bosses go he gives me a lot of latitude. That said I do have better things to do then to worry about whether I offended yet another player because they didn't like my opinion an can't sperate me as a person from me the THD guy.
Funnily enough the running joke around here is... "Andy, you're phone is gonna ring of the hook today"..."why, who's Wheaties did you piss in this time?"
