Simple but effective noise reduction. Now you can crank the gain on your favorite distortion / amplifier to the limit without fear of creeps and noise! Only one knob controls the level of noise cancellation, and the design of the NR-10 allows you to effectively use the pedal both at the beginning / end of the chain and in the amplifier loop. To avoid background noise or hum, use only YERASOV AD9-100 or AD9-400 stabilized power adapters.
