Hey everyone, this is my first post!
I just got a used MT 15 at Guitar Center about a week ago at an amazing price (for today's market anyway). Its in mint condition, and its one of the earlier models that came with 6L6's- and all the tubes appear to be stock.
My only concern is there's a significant hissing noise that happens on the lead channel only...sounds like static or like a waterfall. The clean channel is quiet and crystal clear. It's pretty noticeable when you're not playing, and even turning down the volume on the guitar doesn't help, its all in the amp. I only run the gain on the lead channel at about 10 o'clock or so. I know some high gain amps have this and that it can be normal, but I just wanted to check and get some opinions.
Considering a tube swap, maybe some 12AU7's or 12AT7's to lower the gain threshold a bit and maybe that will help quiet it down? I tried searching but couldn't find anyone who had the exact same issue, seems like a lot of folks have noise on both channels.
Any help is appreciated!
