I have a Fender 2x12 Hot Rod Deville. The clean channel seems to be working fine but the overdrive channel is not. I have to turn it up all the way in oder to get just a little bit of sound. So that tells me it's working a little. I don't know what to do. Is it a tube problem or something worse? And if it is a tube problem which tube would it be and why would it be going bad?

I had same issue said rrrrrrrrrrrrrr lol and bought new ruby tubes and im jamming once again

For the Drive channel you need to use the Drive control AND the MASTER volume control. When the Drive channel is active, the Channel Indicator lamp should be RED indicating the Drive Channel is active. The Drive control knob is used to adjust the preamp volume and distortion level of the Drive Channel. This gives you a clue as to what to check if adjusting the controls doesn't work -- the preamp tubes. Having said that, ONLY try to check these tubes with the amp OFF! Never stick your hand up into the chassis of a live amp. It could be lethal. Your preamp tubes are the ones farthest from where the power cord enters the chassis. They have a rubber like stabilizer on them. They have a tendency to wiggle loose, which is part of the reason for the stabilizer. Again, if you're not familiar with the insides...stay out and get an amp tech to help you.

The Normal Channel only uses the Volume Control to adjust volume.
