Dynasonic / Buzzing when touching the pickups case

The metal cases for Dynasonics are usually not grounded, you could benefit by adding a wire from the case of each pickup a ground point in the guitar. That might solve the problem.

I would check with a multimeter to see if they are grounded first, and if not I would temporarily clip on a wire from the case to a ground to see if it solves the problem.

 

i noticed something similar with some pickups when i was going through loads and trying them in my tele neck position.(strat type pickups)..some do some dont...it is a grounding issue..as has been said
you could do it by adding grounding to the covers...bit of a tit on with hollow bodies...if it was like it new i would be taking it back and put the responsibility onto them....its another case of supplying faulty goods because no one complains...if it was a kitchen appliance or a car you would be straight on the phone shouting and growling at them
i know i would...i got a free guitar by complaining

 

then im afraid its something you may have to live with...but it is annoying when things buzz when you know deep down they shouldnt

 

Yes, that's always tricky. I would try to attach the ground wires to the pot closest to the F-hole, you may be able to get it out without having to take out the whole wiring harness. Or maybe try to access the wire that grounds the bridge, usually at the tailpiece near the strap button. You would have to unscrew the Bigsby, and run a second wire from there to the pickups.

 

ive heard a lot off bass players moan about this too...many use clear nailvarnish or something similar to stop them touching metal...that could be another possible solution
old guitars were noisier in general ...old amps were less sensitive than modern stuff too...which would make odd noises less noticeable...a lot of modern gear is too clinical and sensitive to outside noises

 

No prob mate...anything to help a frustrated bud!!

 

so have i my friend...so have i
had an amp that kept dying...then get it fixed...then it would go pop again....usually halfway through a gig...always took a backup luckily enough...but that old thing...lovely sounding and as reliable as a £1 watch
nearly put a Daneaxe through it on more than one occasion

 

You don’t need to get to the pots to ground the covers.
Each pickup has one wire going to hot and the other wire going to ground.
Just pull out each pickup and figure out which is the negative/ ground wire and solder that right to the base which is soldered to the cover.
Might be tricky if the wire coming out from under the cover is one insulated wire so you can’t see the two conductors.
Gretsch has made many versions of that pickup not all the same, but it’s probably got a coaxial wire with the ground on the outside, so you could just gently slice off a little jacket and solder a grind wire to the braided shield.

 

thats why i put the Daneaxe down at the last moment...then got it fixed properly...instead of patched up enough for the next gig
but for that moment.....grrr...BerserkerWulf

 

Older dynasonics often have a metal base plate but the newest does not, so you’d need to solder or secure the ground wire to the flange. They have an obvious ground and hot lead though.

 

What year is the 6120?

Some have a handy tab on the base holding the wire against tugging.
It’s possible to use one of those little washers with a solder tab you just sandwich between body and pickup flange with your ground soldered to the washer tab, if the pickup has none.
