To anyone that has one for these babies or has had one.

I just got one and I love it, but there are some issues, 1st when I switch from the clean chan. to the dirty chan. and vise versa there is a popping noise. and 2nd when I turn the reverb up passed 4 it starts to hum, I can't hear it when I'm playing but when I stop I can hear a loud humming noise.

Any thoughts, or knowledge on what this is and how to fix these two problems, other than these two small probs I love this bad boy.

Help.
