The NUX NDO-6 Queen of Tone Dual Overdrive effects pedal is made for guitarists looking for classic overdrive tone with modern flexibility. On the left side of the pedal is the Horseman with Silver mode. The Horseman is based on the legendary Centaur, with a modified circuit to access the secondary function by simply holding down the foot switch. Carve out your tone with the output, treble, and gain knobs, then try switching between the two modes. Gold mode mimics its classic predecessor, the transparent Gold Centaur overdrive pedal. Silver mode is a powered-up version with an extended gain range like the Silver Centaur. On the right side of the pedal is the Morning Star with Shine mode. Based on the legendary Bluesbreaker circuit, this mode offers a very transparent low-gain drive. Like the Horseman, it also features a simple foot switch hold to engage the iconic Shine mode for a crystal-clear treble boosted tone. By using the versatile routing and toggle switches, you can adjust the order of the overdrives. On the back of the pedal, you will find switches for buffer-bypass or true-bypass, and the option to engage an input FET stage so you can increase the input signal and drive your tube amp to the edge.
