A complete DIY kit that will significantly reduce the hum and noise from your electric guitar or bass. It is particularly effective on guitars with single-coil pickups (e.g. Fender Strat) but even guitars with humbucking pickups often have unshielded wiring, pots and switches, and will benefit from this kit.

In a live situation, buzzes from lighting dimmers and transformers are greatly reduced. In the studio, the improved signal to noise ratio makes everything easier— you'll spend less time walking around the room or spinning on a chair trying to find the sweet-spot where the noise nulls out! And the guitar just sounds better - low level harmonics that were previously buried in the mains hum and noise are now audible, making the overall sound richer and more dynamic. I have supplied many hundreds of these kits - people are amazed at the improvement it makes, especially on the DIY "build your own guitar" kits that are popular now.

The outward appearance of the guitar is unchanged. If you are comfortable with changing strings and using a screwdriver, pair of scissors and a paintbrush you'll find it simple and straightforward to fit.

The standard kit includes:
- Conductive graphite shielding paint (30ml)
- Copper foil (self-adhesive, 30cm x 20cm) for plastic scratchplates & control covers
- Accessory pack with brush, cleaning wipes, stirrer, insulation strip and detailed step-by-step photo instructions
- Terminal block to reconnect the wiring without soldering (this is optional, you can solder if you wish!)
- Email support

You can add extra paint, foil and accessory kits to your order - the components are listed separately. Shipping on extra items ordered with the kit is FREE. You can also a request a custom order.

If you want to hear the difference, check the video in the "about" section of the shop. The 3D graph in the last photo shows the effect of the kit on an untreated guitar. The noise at all frequencies is considerably reduced, especially the really annoying buzz from the lighting dimmer (blue peak). Some mains hum remains (light green peak). This is unavoidable with single coil pickups. The only way to reduce it further is by shielding the pickup covers, but most people would find this unacceptable as it will change the sound of the guitar - some of the top-end clarity and attack will be lost. (This is why you often see Telecasters with the front pickup cover removed). And the hiss? Well, hiss is usually due to the electronics in the signal chain, not interference. In this case the hiss is my 30 year old valve combo.... sounds great when you actually play something though ;-)

Please note: All guitars are different - the degree of noise reduction you obtain from fitting this kit will depend on several factors, e.g. pickup type, internal wiring layout, and any shielding already fitted (existing shielding paint may not be obvious), so please check your guitar before buying, and if in doubt contact me for advice.

Very pleased with the product, and the seller was lovely to correspond with. This photo is with one coat and an overnight dip at .3 / .25 - nice, even plating and shine. Thanks!

I use this paint to electroform jewelry and it turned out amazing. I received my paint today and this was my first piece I made. This paint is more conductive than the paint I used before. Highly pleased with this product. Thicker and easier to control, not watered down like some other paints I've used. Worth every cent. Thanks so much for making quality paint. Came quickly too for coming from the UK. I am excited to finish all my other projects.
