TC Electronic NDR-1 Nova Drive. Functionality confirmed. Includes adapter and instruction manual (printout). This is a programmable overdrive/distortion pedal that digitally controls the distortion of an analog circuit. There are several types of analog distortion that can be preset, and the NDR-1 Nova Drive was highly rated in overseas comparison videos. I liked it, but I am selling it to organize my equipment. The included adapter is CLASSIC PRO DC12V 2A 2.1mm. Of course, its operation has been confirmed without any problems. There is no noise from the adapter. The NDR-1 Nova Drive is 12V DC powered, so it is best to use the included adapter, but if you are supplying power from a power supply, please use one that can output a voltage of 12V DC and a power of 380mA or more. The instruction manual can also be downloaded from the manufacturer's website. Although there is some wear and tear, overall it has few scratches and is in good condition. Velcro is attached to the back. Please check the photos for details. I am selling this as a used item, so please refrain from purchasing if you are sensitive to such things. Please read my profile to prevent any trouble. Thank you very much. "Excerpt from the manufacturer's explanation" The TC ELECTRONIC NDR-1 Nova Drive is a digitally controlled, analog circuit overdrive/distortion pedal. It combines the high-quality drive sound that can only be produced by analog, with the convenience of preset functions and MIDI control that are unique to digital control. The dual-engine overdrive/distortion circuit can be routed freely, allowing for a wide range of sound making, from clean boosters to intense distortion. It is an item of great expectation that gives a sense of great potential.
