I have literally stopped using AmpliTube and now exclusively use JamUp Pro. The main reason is due to a hissing in the background that I can't get rid of. The problem is I have contacted customer support about it multiple times, because the hiss is not in any other amp simulator app that I use...only in AmpliTube. I have explained this to them, but the conclusion IK Multimedia keeps arriving at is it is my equipment's fault...even though I don't get hiss in any other app that I use. The noise gate works for the most part, but you can still hear it when you play. I don't have any effect or amp
