Hello ThoGo,
Bottom line, you should not be experiencing any degradation in the signal whatsoever, so it’s possible something else is at play. Can you be more specific with the gear you have before and after the H90? If you single out the H90, do experience the same issue? (Guitar > H90 > amp).
Always good to make sure you’re using the latest version of the firmware: 1.9.10. You must have download the latest version of H90 Control to update it: 1.8.16
