Kinman pickups are fully shielded, as are their leads, so shielding in the pickup cavity is not essential but may be helpful.daysleeperjeff wrote: ↑Wed Jan 04, 2023 7:50 amI’m putting these Fatmasters in a custom build. In your experience do you think it would still be necessary to do a proper copper shielding job in the routes? I know hum and buzz are two different issues and I do want this guitar to be dead silent for studio work.
Or do the pickups alone kill all the noise?
The switches, pots, and jacks are a different matter. You need those to be shielded if you expect silent performance, so shielding the control cavities is a minimum.
Personally, if I'm shielding the control cavity, I'm going ahead and shielding the pickup cavity anyway for completeness, but with these pickups it "shouldn't" be necessary.
For the record, my Jaguar has just the vintage shielding plates which don't cover the sides of the routs, and it's basically silent, and those split the difference between a proper Faraday cage and an unshielded guitar. You've got the control plates and under-pickguard plate on top, and the brass plates on the bottom.
I'd just go ahead and do a copper tape shielding job when you install the pickups. Might as well go all the way. I found an Elk brand of copper tape on Amazon for like $10 that has a conductive adhesive and is large enough to shield multiple guitars. After having used Stewmac copper tape and hardware store aluminum flashing tape in the past, this Elk stuff is the best stuff by far. Equally easy to use as the Stewmac stuff, but as cheap as the flashing (whose adhesive didn't make reliable connections).
