Reason Number 2: The aluminum pickguards and control covers with our built-in grounding rings provide shielding, grounding (when properly incorporated into the shielding solution). Shielding protects your electronics (tone) from fluorescent and halogen lights "hum" found in many clubs and venues. Noisy aka dirty electricity can also effect your electronics and electrical circuits.
EMI (electro-magnetic interference), RFI (radio frequency interference) and even Cell phone interference are sources of everyday tone killing interference that can be experienced in today's world. A Tone-Guard® pickguard or control cover protects against hum caused by single coil pickups. Reason Number 1: Metal pickguards and control plates have the effect of reducing interference in your tone circuit. As soon as that tin foil gets scratched, enough, or at all, it is almost useless in blocking out any rampant radio interference, static, cell phone interference, 60 cycle hum, or other modern day tone killers.Īluminum pickguards are the best solution for reducing single coil hum and other irritating and un-wanted noises coming from your electric guitar's pickups and circuit. You (or your Tech) may have noticed that there is little to no shielding present on the vast majority of today's guitars, except for maybe some tin foil glued to the underside of your pickguard or control covers. In most materials the magnetic moments of the electrons cancel, but in materials which are classified as paramagnetic, the cancelation is incomplete.Īre you are like the other thousands of guitar and bass players out there? These materials are said to be paramagnetic and follow Curie's law:Īll atoms have inherent sources of magnetism becauseĪnd electron orbits act as current loops which produce a magnetic field. Some materials exhibit a magnetization which is proportional to the applied magnetic field in which the material is placed. The information presented below is an exert from: Plastics, by their very nature of being non-conductive, do not attenuate EMI and require shielding systems be incorporated to ensure reliable pickup and tone circuit performance. Most plastic is virtually transparent to EMI / RFI radiation, meaning they don't do diddly to stop the interference. Federal Communications Commission or the EU dictate standards for both emissivity of EMI / RFI and sensitivity to interference.Ī note about plastic pickguards vs. Shielding from EMI / RFI is done for two primary reasons: (1) to keep your electronic device from interfering with others, or (2) to keep other devices from interfering with yours. In short, almost all electronic circuits develop some level of EMI and / or RFI. The clock in your computer oscillates and produces interference. Sensitive components and circuits can be disrupted by interference from sources like power supplies, fluorescent lights, electric motors, switches and relays, even IC's. Electromagnetic radiation and radio frequency radiation are all around you! Their effects on the human body are the subject of fierce debate, but their effect on electronic devices is clear. Why do I need to bother with shielding my guitar?ĮMI / RFI stands for ElectroMagnetic Interference and Radio Frequency Interference (RFI is just EMI over the range of 1kHz - 10GHz). Read more information below or follow the Wiki links below, and find out the answers to the following questions: We did the research, experimented and came up with what we believe are the best aluminum pickguards and control covers for your electric guitar. Heck, we didn’t make this stuff up just to sell you something. Made of aluminum, these pickguards eliminate 60 cycle hum, shield against EMI / RFI interference, eliminate static noise and they look beautiful.
