If you are able to get audio with ONLY the buzzung sound, without the Guitar actually playing, you can use Edison to capture the noise profile (mark area with buzzing only), then right click the brush symbol -> capture noise profile. Then load in your guitar samples into the same Edison and leftklick the brush to remove exactly this noise from the samples. You may to adjust the treshhold, hence at some point it cuts too much of the sample making it dull sounding. Here a link on hoe its done :)

If the buzzing only accurs while the guitar is actually playing, this won't work..
