I think you might have more H9s than anyone else at this point by the way. It's not uncommon for people to have a couple nowadays, and every now and then, I run across someone with three. But four H9s?!! You should send us a photo of your pedal board one of these days. Our marketing guy will lose his mind.
+1 would love to see the photo.
the most I have seen on one shot is Dwezel Zappa with 3 H9's
