Darkglass Element Cabsim/Headph. Amp

I use it for quit practice at home and it sounds great.

Run my pedals and amp through it and it sounds awesome. (Make sure you have a class D amp though)

I've tried everything to make it sound better: I've updated the firmware, I've changed the power supply, the patch cables, the headphones, the guitar... but nothing: volume is super low, there's a constant noise when playing. I'm super disappointed, because the build quality is very high and I've heard a lot about Darkglass. My idea was to go ampless but at this point I am going to stick with my amp.

I like everything, a good thing for home, studio and concerts. Carrying your sound everywhere is cool. Thanks.
