Hello friends! I recently purchased a Pignose 7-100 but I can't get good clean sounds as there is some fizz in the background. Is this normal in the Pignose? Is there a way to fix this fizz?
I am attaching a video where you can hear this fizz.

I'm not in the know about that amp but I'd guess the circuit is basic and the fizz maybe just the way they come.
Being a basic unit, Crossover Distortion of the power stage is likely the issue.
If you can dig up a schematic for that amp and post it, others here might be able to help tweak the circuit for you.
Phil.
