  • How to ground shield your guitar (removing the buzz with a Faraday Cage)

    I shielded my Rickenbacker bass about 35 years ago, and used a few tricks that I learned working in the Aerospace business for the last 40 years or so. One important thing is to remove the wire going to the bridge from the electronics. If the AC outlets you're amp is plugged into aren't wired correctly, and you touch your lip to a mic you can get hurt really bad - it can even kill you ! It has happened to musicians in the past. Zapped - dead on stage! Don't believe me - look it up. I've done about 50 or 60 guitars in the past years, and they've all been AMAZING ! I can stand about 6 inches in front of my amp with my guitar facing the speakers with the volume up and not even feed-back a little. I can hear a difference in the tonal quality of my guitar also.

If the AC outlets you're amp is plugged into aren't wired correctly, and you touch your lip to a mic you can get hurt really bad - it can even kill you ! It has happened to musicians in the past. Zapped - dead on stage! Don't believe me - look it up. I've done about 50 or 60 guitars in the past years, and they've all been AMAZING ! I can stand about 6 inches in front of my amp with my guitar facing the speakers with the volume up and not even feed-back a little. I can hear a difference in the tonal quality of my guitar also. And never any EMI-RFI interference - nice and clean always. Another little trick I use is to use solder lugs on the pots instead of soldering wires to the back of the pots. Makes it easy if you have to replace a pot and not have to put a lot of heat on the pot. I run a wire from all the lugs to a crimped solderless lug and use small screws to attach all the ground wires to the bottom of the electronics cavity. I also shield the hole where the output jack is, along with the cavities around the pickups. I use adhesive backed copper tape on the whole box I build in the guitar, and found that if you use a pencil with an eraser you can rub the tape into the corners of the cavity really easily. I'm hoping to send along some photos of the basics I use. and a few shots of my studio. Hope I can get them downloaded ok. Thanks for letting me ramble on a bit. Also back around 1975 I built a professional quality audio and video recording studio and I've learned some neat stuff over the years, and I'll try to pass on some of that info in another posting.
