Where is this humming/buzzing coming from?

    Hi,

    A year ago I purchased a ESP LTD D-5. Nice bass I have to say. Anyways, about 6 months ago, I started to notice a disturbing humming/buzzing (really still don't know the difference between these two "different" phenomena) at a relative high freq. To deal with it I have to reduce the bass treble tone (which is frankly not my favorite set up). I have been researching around this issue in the web. Well to expedite, last night I checked the ground (according to the Seymour Duncan procedure) path. No issues found.

    Well, I would appreciate any help on this matter, such as:

    Any other test I could run?
    Any known issues with this bass mode/electronics (I know he runs on two proprietary ESP HB and a G & B 3B Equalizer)

    Regards!

    Does it happen everywhere? The root cause of things like that are often dimmers or power supplies for other appliances in a building.

    Yep, at least with an Ampeg STV4 Pro and with a Fender Rumble 500....

    Any difference if you touch the strings or not? Or the sleeve of the jack plug?

    Good question. I haven't check whether is one or the other (string-wise....). Jack position does not matter.
