Default Piezo feeding back on stage.

Taylor DDX, with the stock pickup > Aura

Was playing pretty loud with bass and drums at a small hall and the guitar was feeding back.

What's the solution? Sunrise sound hold pickup for louder volumes?

Hi knuckle...

Several possible ones, the easiest being to bring down the stage volume and take your guitar out of the floor monitor directly in front of you. Then run a stage amp (or monitor) from behind.

Magnetic pickups like a Sunrise are more impervious to feedback but the least acoustic sounding pickups.

Another is to go to an electric/hybrid guitar which will not feedback easily.

All of LJ's remarks are dead on! I would add "cut the mids" as a layman's first thought.

For playing acoustic guitar in a loud rock context, soundhole pickups work best.

The Fishman Rare Earth or the Baggs M1a are the two most popular, since they sound good - very good, actually, for pickups - and they don't squeal like a P-I-G when the going gets loud.

One option (if you can afford it) is a preamp that has both a pre and a post eq output. Pre gives the front of house the raw signal that he or she can shape according to the venue's needs (or yourselves if you're doing self-op), post eq is the signal that you shape with a notch filter according to your (and the monitor's) needs.

If the hall itself was very resonant (like a church or anywhere with reflecting surfaces) it could be that the offending frequencies were coming back and affecting your guitar. In which case a preamp (again) would be a good idea, using the notch filter to find the sensitive frequency - and as the room itself may be amplifiying those frequencies, by notching or scooping them out it will actually help the guitar sound more natural in the room. Shaping the final LR eq can also help by smoothing out the effects of the room on the subjective sound.

Since getting a Planet Waves feedback buster, I haven't fed back once.
A solution that's cheap and simple: my favorite kind.
