Hey all,
First of all, I figured out what was causing my problem, but I'm stumped as to why it was happening.
I have a preset with a Rhythm and Lead snapshot. They both had the horizon gate first in the chain at a sensitivity of 2. I updated the sensitivity of the gate to 0 on the lead snap only, to stop sustained notes from cutting out, but left it ON because it was stacked on the same switch as a compressor which was turned off. So if I just turned off the gate, the comp would turn on which I didn't want. (I realize now that I can likely turn the gate off individually in the signal chain.) So on the lead snap, gate was on, but with sensitivity 0, so in theory it's as good as off and wont alter the tone right?
Well at my very next practice, I cranked up to about stage volume and switched to the lead channel which has delay, and when I cut off a note I got this nasty squeaking/squealing type of sound, that also had this weird filter/out of phase type of sound that got more pronounced as the delay went on. My band mate described it as a cone filter. The delay seemed to stack that squeaky noise on top of itself until it was unbearably loud, and didn't stop till I switched to clean or turned my gain down (which is only at 4 btw).
I had forgotten about turning the sensitivity of the gate to 0 before that noise happened. Was racking my brain at that point, thinking the delay was causing it, preamp tube went bad, etc. I remembered later about it, turned the sensitivity to 1.5, and then the phasing/filter type sound, as well as the squeal were both gone.
I don't have much technical knowledge on effects. Is it just that you can't have a noise gate on with 0 sensitivity in the HX? Not sure why that would cause issues.
