I'd recently bought and installed a set of HDNs - as much because the EMG HZs weren't great, but also due to a buzzing issue with the guitar.
Unfortunately, after re-wiring it's still there... The odd bit with it is that the guitar's volume control causes the buzz to get a lot worse when it's turned down to about 60%-80%. I've checked (multimeter) and the bridge ground is OK - I just can't get my head round what's happening.
At this point the guitar is about to be re-named 'Monty'
Dodgy pots or switches?
