I've been running my iRig stomp and Amplitube IOS through my Egnater Tweaker with wonderful results for some time.
Last night I bought a new Fender Blues Jr and hooked up my iRig stomp and iPad to it. It was terrible. It acted like I had a delay pedal hooked up to it. The sound went in and out and would not stay consistent.
Why would it work fine on my Egnater Tweaker but not at all on the Fender Blues Jr? They both use pretty much the same tubes.
