I am having an issue with my telecaster. I am running a clean sound but it is very noisy. I have to run my noise filter up a lot so that you don't hear the hiss from my guitar. I am trying to get the volume loud enough that I have some headroom on my mixing console gain. If I run it through my amp then I do not have the noise. If I direct out of my hd500x then there is a major hiss. What might I be doing wrong. Thanks for your help.
