ES2 feedback

[ats88]

I was playing a gig last night with a GA w/ES2 that I've played plugged in before without any issue, but last night there was this very strange feedback. Not the high pitched squealing kind, but this low bass feedback that became like a very loud hum. I had one of those feedback buster soundhole covers in. The feedback stopped if I muted the strings. There were a few others playing there, and I didn't hear this feedback from any of them. My guitar was the only Taylor.

Couple things about the room setup - it was a very strangely shaped room, like a very long triangle, and the stage was at the apex of the triangle. There weren't monitors, but the speakers above me were close enough that I could hear myself pretty well.

So was this just a bad sound guy? Why was it only my Taylor that was affected? Why didn't the soundhole cover prevent this? A friend mentioned that the sound guy might have just had the bass up way too high. If this happens again, can I reduce the feedback by lowering the bass on the ES controls?

Thanks!

Could be the sound guy, certainly. Floor monitors or IEMs?? ...as loud wedges can easily result in what you're describing.  Also try inverting phase so the guitar's top is out of phase with the house speakers. Lots of DI boxes have that switch.

Acoustic guitars are always a challenge on stage with feedback. The way I control it over the phase switch and sound hole covers is playing through the Fishman mini and having a line out to the audience speakers with the guitar very very low in the floor wedges mostly relying on the amp behind me as a guitar monitor. And I play loud rock in very noisy bars, it works for me.
