Last night I was rehearsing at a church that just recently upgraded their sound system to some nice JBL gear. I was using my Line6 Lowdown 150 amp at average stage volume on a typical church "stage" (hollow box about 30 inches off the floor). Well basically every note I played the whole night I was hearing that note, and then almost as loud, the note below it. Even down to low Es and Fs. Very unnerving. The guitarist noticed it too and asked if I was running some kind of effect (I wasn't).
Is this sub-octave effect some sort of audio trick the room is playing on me, or should I push the issue further with their sound tech? I asked two guys at the church if they had any kind of octaver effect engaged on their system and they said they did not. I am just "guesting" there so I don't want to be too aggressive on the point but it was driving me nuts!
FWIW, the main P.A. cluster at this church is all flown from the roof (including the sub - when will churches realize that subs belong on the floor), in the center of the room with one three-way cabinet flown on either side to cover the wings. The room is about 350 capacity and is an octagon shape.
Any insights would be appreciated.
