Les Paul Studio - looking for 'Forever' pickups

Re: Les Paul Studio - looking for 'Forever' pickups

Perhaps not the best soldering job?

Too much spare cable? Is there a way to shield this cable like the Gibson braided wire?

Re: Les Paul Studio - looking for 'Forever' pickups

It's funny - all I wanted to do was buy myself some new pickups for my 40th birthday. It's turned into an odyssey of tone discovery. I have not only changed my pickups, but have discovered new tones, rediscovered unused amp settings, rethought my pedals, changed to 50s wiring... and now I'm addressing power and shielding issues for the first time!

It's likely that I just never noticed the power issues before, but I think my tech did some sub-par soldering, as there was a lot of noise. I touched up the soldering which fixed it somewhat, and there is now only a slight difference when I touch the bridge. However for the first time I am getting a nasty buzz (not hum) when the axe is at certain angles to the amp. I've never really had this before. It could be because I scraped a lot of the side shielding from the HRD when I put the chassis back in after speaker change.

I've ordered some copper tape AND some conductive paint. I plan to shield both the cavity and the sides of the amp around the chassis.

I also have quite long leads coming from the triple shots... could this be acting like an antenna?

Does the hum go away when you turn the guitar volume down?

Ok. Do you have any way to test the rig in a completely different location/power supply, etc. Need to see if it’s the rig or environment that’s the biggest culprit.

Tough to see in your pics but do you have a grounding wire running from the bridge to the output jack and touching each pot along the way? Without looping the cable back onto a pot that has already been grounded?
 
Re: Les Paul Studio - looking for 'Forever' pickups

I don't at the moment, however the amp is in the same position and using the same power as before the pup change. I noticed that it was noisier when I got it back from the guitar tech with the new pups. It's possible that I just never noticed how noisy it was before, but it's a pretty prominent buzz....

No, it doesn't have this and didn't before. I believe it is relying on the grounding plate for this. There is a wire coming from bridge and soldered to the volume pot case. That's the one I put more solder on because it looked a bit dry. I also believe this is working because unless I put my hand on the bridge I also hear a high-pitched oscillation!

I just tried it in a SS amp on a different power outlet, same problem, so it's not the damaged shielding tape in the HRD.

Just found this....I’m sure you’ve got a diagram already but maybe you see something here you might have missed?

Thanks, all I have changed is to wire the caps to the middle volume lug instead of the outer.
 
Re: Les Paul Studio - looking for 'Forever' pickups

Hmmm... without being in the room to hear it, I’m running out of suggestions. That said, given the noise changes when you touch the bridge, I’m suspicious of the bridge grounding wire. It might have broken or is not making contact with the bridge stud. If it were me, I’d test for continuity from the bridge to the grounding wire in the cavity. If there’s none or partial continuity, I’d give bridge wire a tug from inside the control cavity - see if it’s come loose. If it doesn’t come out, I’d pull out the bridge stud to see if the wire is making contact or not.

One of the pots had a loose lug so I decided to rip the whole lot out and start fresh. Now to decide whether to keep the ground plate!

Nah. Cts 500k pots, keep the caps, and run a nice, clean ground strap around all 4 pots, with the bridge ground connected somewhere.

Just make sure to avoid a ground loop.

thats what i do as well, the plate can go
 
Re: Les Paul Studio - looking for 'Forever' pickups

Quick question: if I touch the pickup output wires (white/black) to the tip/sleeve of a cable connected to the amp... and there's STILL hum.... does that point to a problem with the way the pickups are wired? And where would the third naked cable go if I were to do this, to the bridge ground?

When I say hum... I know they will always hum.... just not excessive buzzzzzzzzz.....
 
Re: Les Paul Studio - looking for 'Forever' pickups

Alnico 2 PAF's (choose your brand,) lower the bass side of your neck pickup.

What pickups are these? Are you pressing the wires to the cable with your fingers, or holding the wires by the insulation so that only the conductors touch the cable?
