ok, i've done a search to try and make a diagnoses, but i'm not really sure.
My problem is that with my new rig, new gt-8 going into the return loop of my engl screamer combo, feedback is just unbearable in high gain settings. But when i mean high-gain i don't mean high volumes, i just mean rectifier emulation with a metalzone pedal emulation for example. i keep the level so they match the other presets volume.
The fact is that when i choose other emulations i don't get that issues, but when i use too much distortion, no matter what the volume is i get so much feedback i cannot handle my sound.
i don't know if it makes sense, but for me the feedback should be joined to the volume, and it's not that much volume.
i´ve tried moving around, giving my back to the amp, playing side to the amp, different angles.
i don't think is the guitar or the cables, as i just have this problems with for example the stated combination, so i suppose it's just my ignorance. do you know what a problem could be???
thanks for any suggestion.
