Harley Benton Parts Copper Shielding Tape

The quality is pretty great, the adhesive is a good balance between stickiness and ability to work with, it is easy to cut with scissors or craft knives and it stays in position very well.

The only downside is that it is quite little tape. For Telecaster body cavities + pickgruard I needed roughly 1.5 rolls, for a Stratocaster + pickguard 1.5 rolls were not enough, I'd probably need about half to 1 roll extra to cover the entirety.

Petit rouleau en effet mais c'est précisé dans la description du produit.
Avec un seul rouleau j'ai pu faire mon pickguard et la plaque arrière du tremolo, et il m'en reste encore. Impossible de faire les cavités avec cependant mais ce n'est pas mon objectif, mes cavités ayant été peintes à la peinture métalique. La couche de cuivre est selon moi un peu trop importante pour l'appliquer dans les cavités facilement (pas assez maléable). Mais sur du plat, c'est tout bon.

Easy to apply, stays attached

it conducts very well but in some circumstances it is best and/or easier to use conductive graphite paint.
the adhesive is a bit weak and the surfaces must be dust free and well smoothed.
the latter might have higher resistance if not properly applied though.

This is a thick, high-quality shielding tape. The thickness helps a lot as it makes the tape quite stiff, it won't roll back on you as you remove the backing. The only problem is that the roll is quite short, not quite enough for a Precision-style bass's cavity.

Highly recommended, just keep in mind you might need more than one roll.

You need too as was my case with my strat a righty switched to a lefty and took me 2 rolls for being able to create that faraday cage.

Check the dimensions pic makes them look Gaff tape size but think smallest roll of cellotape .
That said works well and easy to fit.

4 cm is the size from up to down. So if you need a lot for your guitar by many.

If only it was enough tape to cover all the internals of the guitar

Great product, the tape sticks well, it is good quality.
But it is not enough for most guitar shielding applications.
Buy 2 instead of one :)
