    Feedback. Jimi Hendrix, Ted Nugent and others were famous for it.

    Guitar into fuzz & cranked amp will make that noise; that often fishtails into feedback

    that's a loop where the amp is amplifying a note then itself indefinitely...(like when you're talking into a mic & the noise gets out of hand)

    you do need a cranked amp (kneeling before the speaker facilitates the effect immediately)

    classic rock :)

    Here's the noise, that was just a test....sorry That wasn't noise that was sonic mayhem from my last gig. Here is my PR with the ghost note.

    NOtes... I had the amp recapped and serviced a month ago. The speaker is a Jupiter C10n clone and it's well broken in.

    Do you have the pedals on? My first guess would be a tube going microphonic Have you tried other tubes.

    Don't ever apologize for being lazy.

    It's my strongest character trait.

    So if I tap the tubes with a pencil and one of them rings clear as a bell through the amp I expect thats the dud?

    That is a nice sound overall, though.

    I think there s something resonating inside the amp, a loose screw or something of that order. There was a thread not long ago about that. The poster complainging about his amp rattling when he played certain notes. I think that s what you ve. Don t have a cure for it though.

    I had that happen on my old Super. The speaker washers were pretty loud.

    Yup - that's a microphonic tube. Replace it and see if that resolves the issue.

    I've also heard similar sounds with the portion of the string *behind* your fretted finger ringing. Maybe see if you can hear that unplugged, but if it only happens with that one amp that wouldn't be it.

    screw loose, rattly noises that appear suddenly are often a tube going out. my brother chased that phantom in his Hotrod DeVille until it blew up... bad power tubes, rectifier, and took out a couple resistors too

    what amp and which tube is microphonic

    Jim Gaffigan does a funny bit about this, and I paraphrase:

    "Some people run a marathon.

    "If I have to go to the post office and dry cleaners on the same day, I need a nap."
