Here is a noise I keep getting out of podfarm even when the noise gate is on. Also even when I just put a amp into podfarm with no guitar plugged in it starts getting a hiss, is this normal? I'm running my Epiphone Zakk Wylde Bullseye directly into my Presonus Firestudio project. I also have a Countryman DI and the sound is still there regardless of the ground being on or off. Help please. Thanks.
