This test was done in the store through several amps. As I have said previously, In my area most guitarists are finding the same thing. No separation between notes on chords , muddled or choppy overdrive/distortion and often sharp to the point of harshness. This is something I fell Line6 has to work on to resolve. It has a very presentable look to the hardware, even desired, but they need to really do more on all sounds coming from this unit. It has an envelope sound to most amp modals that is the signature of heavy processing. this too needs to go for the 2K or 1K it takes to buy one of these. I am for the Helix in principle. But there needs to be much more work done to make it competitive and palletable at that price. It needs to be stage ready for any genre.Most Helix owners don't want to hear that and have rather crude remarks to anyone providing positive feedback on what needs to be improved. Its competitor, HeadRush, is worse in this regard. when you hear pristine advertised sounds on a product and cant her the same live, it is like false advertisement in a sense and it is very disappointing when your excited about a product. This is the last I will comment on the product, but Line6, you could really be the top player with a bit more work.
