Conductive Copper Tape

You must ground all of the cavities that have been shielded. The adhesive is conductive, I tested continuity. I shielded a jackson dinky double humbucker and a les paul (including the backs of control plates) with one roll. If you have more than two guitars I would get the paint.

I've ordered this tape twice now. The second order was a different kind of tape. It seems a little less robust (although I didn't actually measure the thickness to compare) and the backing is really flimsy, making it more difficult to get a corner started when you peel it off. This seems like a small gripe but it adds quite a bit of time to a shielding job. There are other methods of shielding and, in my experience, none of them work as well as copper tape. Stewmac's tape has the conductive adhesive that is key to a good shield. I swear by this stuff.

high quality product

Very sticky. Good price. LOTS of tape on the roll. Not bad to work with, although I would recomend buying the 3/4" roll as well.

I purchased this copper foil as a last resort for a friend's inexpensive bass guitar that had a persistent noise problem. Covering the entire cavity with the foil and the underneath of the scratch plate eliminated the hum completely. I was so impressed that I did the same for my '02 SG with P90s that was mildly noisy. It worked there very well also.

Really encouraged, I did the same for my '82 Strat and it is now almost totally silent. I'm a believer! Copper coating my Les Paul next. This stuff really works! A couple of hints: 1)The really narrow stuff is pretty useless. 2)Make sure that the foil on the underneath of the guard makes an electical contact with the cavity foil 3)Ground the foil somehow.

I used this copper tape (large size)to try to reduce 60 cycle hum in the pup cavities & inside the control panel of a Epiphone L.P. Special with P90 pups. The tape is pretty easy to work with, & did reduce the hum somewhat- you don't really notice the hum much unless you're playing thru a maxxed out amp with a lot of gain, & don't notice it at all while you're playing.

It's not cheap, but it makes shielding much easier. A big plus is conductive paint, so you can shield cavities one side at the time and still maintain electrical connection between all tape pieces.
One tip though, save the money and get the narrowest tape. Use cheap household Alu foil and double sided tape to shield large surfaces and then just connect all the Alu pieces with the copper tape. You'll be able to shield a few guitars with just one 3$ roll and some household foil.

Orded to shield the control cavity of a Strat/Les Paul hybrid I was rebuilding. Conductive adhesive works flawlesly. I performed many condutctivity tests during installation and not once did I find a failure point.

Easy to apply. A good thickness balance between durability and workability. Easily cut, and molded, but doesn't tear unless handled very roughly.

I used the 2" wide tape and cut widths to fit.

Works great, does what it's supposed to do. Easy to work with and is very thin to put into those small routed areas. Shielded pickguards are not enough to shield properly. You must make a "box" surrounding entire area for low level signals. When exiting box/cavity use shielded cable. Single coils will suddenly be almost totally quiet as full humbucking pickups. Notice the three contact points between pickguard and cavity. When done check continuity w/ ohm-meter to double check all work over entire guitar areas, pots, cavity, strings, bridge, to output jack.

I'm amazed at all of the musicians that shell out hundreds of dollars to upgrade pickups, tuners, bridges, etc… and won’t take the time to shield their primo components. This is really a no-brainer, especially if you’re replacing pots, jacks, wiring and so on. This tape is not difficult use. Goodbye unwanted noises.
