    Cool Guitar Shielding

    I have seen so many threads on this subject but I have whittled it down to 2 main areas:

    1. Covering the cavity walls in either tape or paint.

    2. Connecting everything to ground (or Earth as we say in the UK).

    I have a great tip for people wanting to do a fantastic, professional job on a budget.
    The copper-foil-tape supplied for guitar folks use is a complete rip-off and is so expensive for the amount you get (1 guitar), I object to buying it!
    Paint is also expensive, for the amount you get and the results are usually poor so that's a no no for me also.
    Use aluminium foil-tape instead of the copper-foil-tape, a lot of people do so this isn't a new product for this job.
    Here in the UK I can buy a 10 meter (30 1/2 ft) roll of aluminium-foil-tape for 1, the adhesive isn't conductive but by following advice from other people and folding the edge back before overlaying the next piece you can make the whole covering, in the cavity, conductive.
    Another method is just to just slightly overlap each piece without any folding but then use small pieces of kitchen foil as stitches or bridging pieces glued on with Uhu-Stick (Prit-Stic type glue but better quality).
    This glue is water-based and is conductive.
    You can shield the scratch-plate this way too, you can also use just aluminium-kitchen-foil and Uhu-Stick to do the scratch-plate and cavity but it may take a while.
    If you do use Uhu-Stick to glue on top of the foil you can speed the drying up with the aid of a hairdryer on a medium setting.
    By warming-up the foil it will dry the glue and give a great bond.
    Only use Uhu-Stick to glue stuff-down on a sealed surface, on bare wood the glue will be absorbed leaving the join bare (it will come unstuck).
    For Earthing (ground) use a small square of copper-foil-tape stuck onto the wall of the cavity and by overlaying the edges with strips of kitchen-foil and Uhu-Stick you will make it all conductive. Then you can solder your earth wire (ground wire) to this). This method does look pretty cool too. I can never understand people gluing down aluminium-kitchen-foil using rubber compound adhesive, PVA, spray adhesive, tubed contact adhesive or any other messy liquid glue. By using the water-based Uhu-Stick you get great flat smooth results without the mess.

    I am not commenting on Earthing the guitar because I don't know enough about it and I would like some good information from other members of where to do the connecting without creating ground loops leaving me to potentially 'light-up' myself. not nice!
    So please any accurate information to safely earth my guitar after shielding-work will be greatly appreciated.
    Thanks guys, all the best: Glenn (in the UK)

    When I did my guitars, I used copper tape from the Garden Centre for the cavities. Stuck it down and soldered the edges together in a few places. For the scratch plate I used a sheet of kitchen foil held in place with spray-mount picture adhesive.
    I'm a riddle, wrapped in a mystery, inside an enigma.

    I generally use the copper tape, and like our Captain, I solder the edges together. I put the same stuff on the backside of the the scratchplates to complete the process. I have never yet encountered a problem with a ground loop problem.

    Cool

    I hate any paint as a shield feature, I'm rather with nice self adhesive cooper tape, 2" or so... nice measure, cut and done! One suggestion then is to put small insulate surface (tape or very thin plastic film) bellow electronic to avoid accidental contact of switch contacts with cooper tape bellow, sometimes it occurs, believe me.

    The insulator is a great suggestion. I use conductive adhesive copper foil in my guitars, and when it's installed, I use an automotive product called Liquid Electrical Tape, painted onto the foil which prevents accidental component shorts.

    I use a brand called Blue Magic, but there are lots of them. I was originally buying it from an automotive supply store, but I notice it's becoming a building supply item as well.

    This is a Tele thinline I did with a built-in wireless mounted under the pickguard. After I copper-shielded, I painted the cavity and was able to lay the open circuit board for the transmitter right in with no issues.



    By the way, the brass contact in the neck pocket connects the truss rod as the antenna.

    The truss rod as an antenna?! Dang, Spellcaster you are an ingenious guy.
