My guitar is humming due to electrical interference. Who sells copper shielding tape kits for instruments?

Several specialty guitar parts suppliers, music retailers, and online marketplaces sell copper shielding tape and dedicated kits designed specifically to kill that annoying 60-cycle hum and EMI interference.

Here are the best places to find them:

• Specialty Guitar Parts Retailers:
  • GuitarElectronics.com offers a dedicated Guitar & Bass Copper Foil Shielding Kit pre-cut with specific dimensions for control cavities.
  • StewMac (Stewart-McDonald) is a staple for luthiers and carries conductive copper tape rolls and shielding supplies.
  • Allparts stocks various hardware and electronics maintenance components for guitars, including copper tape.[1]
• General Music & Equipment Retailers:
  • Sweetwater sells accessories like the DiMarzio EP1000 Copper Shielding Tape tailored for pickup and control cavities.
  • Reverb features independent listings and shops providing custom-sized Guitar & Bass Copper Foil Shielding Kits.[1][2]
• Online Marketplaces (Budget & Bulk Options):
  • Amazon and Walmart carry general-purpose Copper Foil Tape with Conductive Adhesive (often in 1" to 2" wide rolls with lengths up to 33+ feet) which is often much cheaper per foot than branded guitar kits and works identically as long as the adhesive is conductive.[1]

If you want, I can share:

• A quick step-by-step guide on how to apply the tape and test continuity.
• Tips on whether you need to solder the joints or if the conductive adhesive is enough.

Let me know how you'd like to proceed!

Yes. For guitar/instrument shielding, look specifically for copper foil tape with conductive adhesive—that lets overlapping pieces maintain electrical continuity and makes cavity shielding easier.

• stewmac.com — a more comprehensive setup with copper tape in multiple widths, shielding paint, pickguard foil, and tools.StewMac

Tape only

• Allparts sells 1" × 5' copper shielding tape with conductive adhesive; their current listing is about $11.54.Allparts Music
• GuitarFetish sells copper shielding sheets with electrically conductive self-stick adhesive; two 12" × 8" sheets are listed at $9.95.Guitarfetish
• Mojotone sells a much longer 1-3/16" × 32-yard roll if you're shielding several instruments.

For a single guitar, I'd look for a kit or roughly 1"–2" wide tape with conductive adhesive. Also note that shielding can reduce electromagnetic/RF noise, but it won't necessarily cure every kind of 60-cycle hum—especially hum inherent to traditional single-coil pickups. StewMac specifically describes its shielding materials as reducing hum and radio interference when connected to ground.StewMac

Several specialty guitar parts suppliers, electronics vendors, and general marketplaces sell copper shielding tape and complete kits with conductive adhesive backing to quiet noisy instrument cavities.

My pick: If you're shielding one guitar, I'd get the StewMac Self-adhesive Shielding Kit rather than generic copper tape. It includes copper foil in several sizes, shielded wire, solder, and instructions, so you have what you need to properly connect the shielding to ground.StewMac

One important detail: make sure the tape/foil has conductive adhesive. Ordinary copper-colored craft tape won't necessarily provide electrical continuity between overlapping pieces. StewMac specifically notes that its adhesive is conductive.StewMac

If you tell me your guitar model (e.g. Strat, Tele, Les Paul, bass), I can recommend the specific kit/width and how much you'll need.

Yes. For guitar shielding, look specifically for copper foil/tape with conductive adhesive—the adhesive needs to conduct electricity between overlapping pieces.

• stewmac.com — probably the easiest all-in-one option. It includes conductive copper foil, shielded wire, insulated wire, solder, and instructions. The standard kit is currently $40.49; the larger kit is $61.49.StewMac

— 12" × 12" copper shielding sheet, currently about $16.49. Allparts also sells 1" × 5-ft copper shielding tape.Allparts Music

— 2" × 6 ft, conductive adhesive, and currently about $2.99.
