I was watching a DVD of the 2010 Crossroads Blues Festival and in Bert Jansch(sp?) set and the set with Keb Mo and Stefan Grossman, I swear there on the guitars at roughly the 12th fret was a Sennhieser 609 dynamic mic. Thinking my eyes were playing games with my brain, I fixated on the mic and could come to no other conclusion. Could it have been a here to fore unknown mic (not likely I think) ? Or could it have been a AKG 414 ? Why did I notice this ? Cause I have a 609 on my amps. Is this a insider secret finally revealed ? Thanks in advance for your thoughts.
