Feedback When Wearing Headphones – Overloud THU Review

I really love the sound of this app but my problem is when I’m using it with just a headset I get feedback when I turn it up to play along with a song in my amazing slow downer app. I tried adjusting the levels in THU and when I get there with no feedback I have to turn down the music I’m playing to low enough to hear the guitar. Then I have to turn my iPad or iPhone up really loud to hear everything and then the feedback starts showing up again. Has anybody else had this issue?
