I had the same problem guys. Its all based on your output and where and how its being sent. the only thing i got to sound good is a carvin rx800 powered mixer and 2 phonic speakers. it sounded terrible. i was ready to return it. I changed my output settings on helix and started creating my own patches. playing without cabs will do this too. It took me 3 days to figure it all out. need help let me know
