Hi, I have an issue where playing some notes in fifth octave like g5 weirdly resonates with some internals of the Amp amifying the note to unpleasant degree at the start of the note and even more couple of seconds later. Notes close to it behave normally.
This happens on both my guitars, both through the speaker and headphones on any cranked high gain Amp. My other two amps do not exhibit the same issue as well as boss gt-1000 connected to my code with ever section of it turned off.
Please help me troubleshoot this.
Obviously, I have updated to the latest firmware and did a factory reset after. However, neither of this helped.
