I am glad to have a new HD pro X in the end of this year, it sounds perfectly!
However, I observe a problem that when the volume of amp models are set above 50% (my setting around 38% to 53%) or applying some EQ effect processing, there often comes some buzz or Ribbing noise sound.
I use digital output (for 0 dB) and set to 96kHz, but the buzz sound are also occurred from the headphone output.
Does anybody has this problem? any solution for this? Thank you so much.
