I've jsut plugged my Ibanez into iRig2 and AmpliTube CS on my iPad.
A lot of background noise is coming out to my headphones, and it becomes significantly worst when I touch the app screen. No metter if I increase or decrease the volume and the gain, the noise caused by the interaction with the app remains (until I unplug my guitar).
I also hear a ticking noise in background, let's say once every 2/3 seconds.
Is it normal? In that case I wonder how other users can use it, even only for training.
