Conductive Pure Copper Tape Double Sided Adhesive Copper Foil Tape for Stained Glass, Guitars, EMI Shielding, Electric Connections, Repairs, Grounding, Crafts (1inch x 66FT)

Conducts through on both sides. Used this to span a small gap in some shielding, worked as expected. A little on the thin side so it tears easily. Other than that happy with the paper backing being easy to remove.

I was skeptical that this would adhere to the inside of my guitar because the surface was not smooth but it turned out to stick well. I confirmed that multiple layers of it do conduct well right through the adhesive also. I measured the back to front on a few pieces and got only 0.4 ohms so the adhesive does conduct well; definitely good enough for shielding purposes. I know there is some controversy about if shielding your guitar is necessary or not, but I can tell you for sure that between this and replacing the pots, switch and jack, my guitar is 100x quieter now. So much so that it is absolutely noticeable the first time I plugged in afterward. If you are having noise issues with your guitar, I would definitely recommend covering the control cavity and cover plate with this to see if it helps. It's a much nicer instrument now.

I use this to tape the ground wire to a conductive RJ45 connector shell when making shielded Ethernet cables. Works great.

I've used 5 or 6 different conductive tapes, from copper to coated fabric. This is great for the price. The paper backing is easier to separate than many brands but doesn't peel off inadvertently. Grips untreated pine lumber very well. Multimeter couldn't detect any impedance across a 12" span. Thin, but copper through and through without coatings over cheaper metal or similar common deceitful practices. This makes it easy to work into tight 90 degree angles. I couldn't test the conductivity of the adhesive as the sharp multimeter probes and thin adhesive make it nigh impossible to determine whether you're contacting adhesive or the underlying metal but it measured the same as the top side. With pine it can be removed with some effort, ymmv If you intend on painting over this, test your paint as slick copper tends to shed paint.

Works well. Adheres properly

I used this on my telecaster after I changed the pickups. It was night and day difference. A real game changer.

Perfect

Good value & great product . Couldn’t source locally . Quick delivery . Patched an RF leak in a faraday cage .
