So i joined a second band. In my first band i own/run the PA which is digital and i dialed out all feedback frequency there. Just easier. Anyway new band already has pa. But older analog. Which is fine sometime we play at bars or festivals that have their own pa.
I play lead guitar but also acoustic when needed so I set up specific performances for all songs and so on. So I am looking at this at the performance level. Like how can I set this only on certain performances and not on others.
So my first thought is EQ it out. So for example i as stated on my PA i EQ it out. But my PA allows me to specify the exact frequency to drop. So like I can say cut1233 and 1220ish to 1240ish get cut with everything around it still there really not noticeable at all to human ears. But no feedback? So question 1 can this be done at the performance level. Like as a effect or maybe somewhere in performance setting. If so I can not find it?
Second. A lot of acoustic people recommend, Sweetwater instructional info etc. Phase invert the wave. Is this possible like with an effect? If so how?
Other options
Thanks in advance
