Okay.. the hum from the reverb circuit is starting to really get on my nerves. It doesn't matter what pickups I'm using ...humbuckers or single coils. Can anyone begin to suggest what I should be checking to remedy this problem?

Thanks!

Try replacing the tube for the reverb circuit. I believe it's a 12AT7?

Reach in the back and grab the reverb tank, move it around in the bag (NOT necessary to remove it), the object is to pull the bag away from the tank where it has stuck to it. Shift it around a bit and see if that helps. I'm not sure how it works but Mesa has those very instructions in one (or more) owners manuals for troubleshooting reverb feedback. Good Luck!
