We have had our Amplifi 150 for about 4 days now, and 2 days ago, the volume almost completely dropped out. When volume on our guitar, ipad, amp, plus all volume sliders in app have been turned to the max, the amplifier goes to about the volume of a mac computer. The damn thing should be blowing out my eardrums. Has anyone else experienced this, and if so, how did you fix it? Sorry for seeming pissed off, it just seems like a massive waste of money. Thank you
