I noticed that at the back of my AC30 there's a rattle/vibration when I hit one particular note. G string 7th fret.

It sounds like it's coming from behind the amp, rather than through the front. It only happens on this note and I can't notice any rattle coming FROM the actual guitar.

I hear they use false bypass switches.

It's, like, so ironic.

Have you tried it in another room? I mean, there could be something in your room vibrating at that frequency.

could be a screw vibrating or a microphonic valve... or something else.

Only on UG would I say I got engaged and bought a jet city and get congratulated on the amp
