Dear all.
I tried yours ideas. I cut in global eq and in the IR the frequencies below 120 hertz and at 6,5khz. The clean is ok but there is still bad noise in distortion with my headphone and monitors Adam F7. I notice that the sound is little bit better but not acceptable to play in live. I verified also the guitar pad was in "on" position. I put the Master volume at 12h. For your information I use the 1/4 trs output and not the xlr output to link with my presonus studiolive live.
I tried also a simple preset with just a tube screamer, a brit plexi brt, a reverb and an IR from ownhammer. I have the same problem with my headphone link to the helix or the presonus and with my Adam F7 monitor.
Tomorrow I Will try the 4 method câble with my laney irt studio and I will use the distortion of the lany.I Will keep you informed.
Many thanks at all for your great support and help.
Regards
