At live shows or studio rehearsals, when I solo with my high gain patch, sustaining notes turn into a squealing feedback instead of a nice natural feedback. Turning the guitar away from the PA speakers do not help.
I use the Placater Dirty model with Gain at 4, HBE on, boosted with a Gain block set at 10db.
I have a similar issue with other high gain amp models too.
Anyone else having the same issue? Any recommendations to solve this issue?
