New to playing with a band and the HX Effects, sorry if there is an obvious answer to this.
I recently picked up HX Effects to use with my MESA Dual Rectifier multi-watt head. I spent some time setting up the effects I wanted at home (bedroom volumes of course) and everything sounds great. However, when I turn up my amp at band practice to get over the drummer, I get a terrible squealing sound, very high pitched type of feedback. The squealing occurs when I turn up the output volume, even if I have the guitar volume all the way down, so it is not feedback coming through the pickups.
I'm using the 4 cable method with a pretty standard setup:
guitar > HX Effects > noise gate > red squeeze > Minotaur > FX Loop > chorus > simple delay > glitz > 10 band graphic > noise gate > speaker cab
The problem only happens when I'm playing through the clean channel (channel 1). In this snapshot I have all of the effects on except the Minotaur. For my distortion channel 3, I turn on the minotaur and turn off all the effects in the FX loop (chorus, delay, reverb) and I have absolutely no issues at any volume. Levels on the effects are all set to zero except the red comp (+3.0, the Minotaur (+7.0) and the EQ (-3.0).
I added the 10 band equalizer (rolled off the highs) and the second noise gate to eliminate the squealing, which works, but they are definitely impacting my tone.
I'm at a loss on what to try next- I've fiddled with most of the settings to no avail. Could this be gain staging? If so, how might I adjust to get rid of the issue? Any suggestions would be greatly appreciated!
