Cut Out The Noise

How would Y'all handel "hiss"?

Not sure of the source of the hiss. But if it is in the file itself, you can turn the Treble or other control to suppress it some. It will also affect the song's high tones.
On the other hand the hiss could be from the way the amp was designed. I can't think of any other way hiss can be caused, except by a weak signal or poor recording.

Don't know if the ground loopback and hiss problems have been resolved but here's some advice just in case..
Ground loop: Run all your equipment into the same power source. I use a power conditioner. IF the supply is wired properly and to a good ground, you shouldn't have a loop problem. In the case of an open ground, I have had to ground lift my Dell laptop as well. Not the best choice.

As for hiss, it is usually a sign of too much gain on a noisey effects processor. turn off the effects and see if the problem goes away. If it does, then adjust accordingly for a happy medium.
