For as long as Fender has been making guitars, players have been fantasising about whether they could ever experience the glorious sound of single-coil pickups without the dreaded 50-cycle / 60-cycle hum.
Experienced players often try the following things:
- Dummy coil (changes the tone dramatically, never for the better)
- Copper shielding (fiddly, messy, time-consuming, can fail at the worst times)
- Noise suppressor pedals (kills sustain and overall tone)
Well now with the Ulbrick NRS system, you can get rid of 80% to 90% of the hum with ZERO CHANGE to the tone of your Stratocaster or Telecaster.
This complicated yet so simple device was invented and patented by Melbourne guitar industry legend Dave Ulbrick, and we're proud to offer it as an option with our Fender guitars.
Why do single coil pickups hum?The magnet of that a pickup is built and acts as an antenna. The idea is that through constant vibrations of your strings, the 'antenna' will constantly pick up the main source of vibrations (your playing). Now, the main problem is that this magnet is powerful enough to capture other sources of currents. Radiation from lighting circuits are two of the main sources of hum. Where do we find these two sources predominantly? In a stage!The way it works is, this radiation generates electric and magnetic fields that oscillate at around 60hz. This frequency wouldn’t be that much of an issue since it is a very low one. The real problem arises due to the fact that besides that 60hz cycle, it will also generate its harmonics. The amplifier will capture all of this and if these currents are particularly strong, hum or even a buzzing sound will be produced.
