Hello just copying from
guitarnuts2.proboards.com/index.cgi?board=pup&action=display&thread=5522
since i think this problem deserved a separate thread.
I had those symptoms :
initially, and after the rails installation i had
1)
a) the tremolo wire unconnected
b) the dimarzio bare wire to the hot (that was obviously very wrong, i was just anxious to listen to the rails, that i did everything in full throat speed, cause we had to go somewhere with the family and i wanted to hear them before our departure
c) the bare wires of the rails were taped along with the white-red wires
effect : ALL pups buzzed *hard* when touched with bare hand
2)
a) the tremolo wire unconnected
b) the dimarzio bare wire correctly to the ground
c) the rails bare wire untaped from red-white and (correctly??) soldered to the ground
effect :
- dimarzio behaved perfectly, BUT
- the rails continued to buzz hard in the exact same way whenever touched
3)
a) the termolo wire *connected*
b) the dimarzio bare wire correctly to the ground
c) the rails bare wire untaped from red-white and (correctly??) soldered to the ground
effect :
- dimarzio behaved perfectly, AND
- the rails stopped buzzing when touching at the same time the tremolo or the strings, (which make up for the 99.99% of the occasions, so its ok as is now), *BUT* still buzz if i somehow manage to touch only the pups without touching anything else grounded (strings, bridge, etc..) So the problem is killed at its generation, but is still there, not
inherently gone.
Update : Just measured the dimarzio rails (fast track I, fast track II) and the artec rails.
well, there is a difference, as i had suspected. The dimarzio rails themselves are connected to the ground,
by testing for connectivity between e.g. the rail and the bridge, there is indeed connectivity.
However when i test the artec, there is no connectivity between the metal rail and the ground circuit of the guitar.
That means that the bare wire of the artec does not connect to neither the rails or the bottom alnico magnet bar of the pup....
Maybe that's why the artec are so much cheaper than the dimarzio....
What can i do?
As a first resort i think i'll swap ground/hot wires (but always with the bare shield wire to the ground). This might make a difference in the buzz. Those pups hum more than other humbuckers. And also this might alter a little the string buzz effect when touched with bare hands, with no other ground metal of the ground circuit touched at the same time.
As a second go, i might try grounding the rails and their magnet.... Does this sound ok or foolish?
