What's the difference between good bass and phenomenal bass? A secret weapon known only by the code name NE-1. Developed by Yamaha over a decade ago for Nathan East, this "magic box" has helped him to achieve his signature sound with such artists as Eric Clapton, Elton John, Michael Jackson and the FourPlay. The NE-1 is a fully parametric equalizer designed to shape the mid-range of a bass's total spectrum. Three "Q" shape patterns allow you to apply creative and corrective equalization. The simple design also includes input and out jacks and a bright LED. Add the NE-1 to your arsenal and take your sound above and beyond.
