IF you can hear the same noise through you "headphone out"

easy one usually! (ex: most of the time)

buy some "real" tuner cleaner, "without lube" like from EZstreet,

or blue shower, any of the expensive ones that don't melt

plastic components.

Dont get the cheap Radio Shack versions, or any of those

from the american hard ware stores. They will ruin your Poly-800 forever.

Then just spray it in the little holes on the volume pot, turn it from

OFF to FULL volume about a hundred times fairly quickly.

If you cant get the tuner cleaner, you can sometimes

get it to work for very short periods of time by just the hundred or so quick turns.

If you cant get inside, you can spray a little right on the metal post

under the plastic volume knob , and it will seep down into the pot.

takes awhile of doing it a few times to get enough to seep in.

OR, your pot is bad, and its a goner! LOL!!!

90% of the time it a little bit of dirt... typical "mature" keyboard stuff.

Hello everyone,

my Poly-800 has been acting up recently.

As I turn the volume knob, I hear a little bit of static (almost like a ground hum). It shifts from the left to right signal and disappears when it's on full volume. Of course this is a problem when recording because when I have a clear signal it's likely that the volume will be too loud resulting in distortion. Does anyone have an idea for a quick fix on this? What could it be?

Thanks in advance!

Dan
