Hey guys, I’m presently in Spain playing some shows and using my HX Stomp. I normally get great sounds BUT have encountered a problem, the place I played didn’t have an amp (which I have settings for) or a cabinet (which I use my Seymour Duncan Powerstage 170 and sounds awesome ) so I had to go in direct to the mixer and it sounded terrible, fizzy and trebly!!! Any idea what could be causing or how I can improve this? Thanks...
