    Hello, I need a little help diagnosing a problem with my Orange Rockerverb amp. So the problem is very specific. I have to use my Gibson Les Paul in the neck position and reverb has to be on. Every time I hit a F note there is a weird metallic noise that slowly tapers off to what sounds like someone do a slow pick slide down the E string. It's really irritating and really loud. I tried a different reverb tank, no dice. I tried seeing if a tube was loose, or any loose screws around the speakers or reverb tank and that also didn't work. I can't tell 100% where the noise is coming from, but it sounds like it's somewhere in the chassis. Any ideas as to what's causing this?

    I would usually suspect a tube but you seem to think it is a vibration elsewhere.

    A quick google search... It appears with the Orange, the reverb tank can pass on resonant noises when certain notes are played.

    You have tried a different tank... Tap on the tubes to see if any are microphonic. If you can recreate the noise, tap on the tubes during the noise to see if it can be interrupted.

    Take the tank out and rest it on a sweatshirt. If the issue goes away, remount the tank with an old mouse-mat as padding.

    I tried a different tank and I tried tapping on the tubes neither reproduced the problem. I think I figured it out. I believe it was the tube shields or one of them. I pulled them out and played for a bit last night and the noise was gone.

    I had the tank pulled out completely sitting on different materials and even in different positions it still made the noise. I think it was a tube shield. I'll check again tonight.
