Hi guys sorry to be painful on this.
My A rig is 2 amps one wet one dry.
My wet amp is fed by a tap from an attenuator into input 2 of the h9.
This is where i first found the issue on the day i got the h9.
I did the video in a loop situation as it was less stuff to double check the problem.
The same sound is produced in both cases.
Im happy to do a video on my A rig to show the problem.
