Hey everyone,

So I've been having problems with my Marshall head. I get volume swell issues, loss of tone and then no tone at all. Seems a bias is a good place to start and I'm finding an issue with that already. My multimeter isn't reading any voltages. The meter works fine, I checked batteries with it and it responds. I have the amp heated, off standby and still no reading. Am I doing something wrong or...?

^+1. If your tubes are jacked up biasing is not going to do much beneficial other than maybe tell you your tubes are jacked up. New tube time, it's my favorite time!
