That's exactly my current situation. I purchased a Hotone Ampero. tested it with headphones, and directly to the mixer and PA with the band. Sounded good, always better with headphones. Also tried it in the Amp in socket of my Katana, not bad.
Got the Headrush and the tone sucks, no matter where I set the speaker, no matter how far or close I'm from it. Thinking about having to create specific presets for the speaker, but will have to do it in my rehersealplace, as I can't go loud at home. That's bulllollipop. Could end up getting rid of all that stuff.
