Thank you for viewing. [Product Overview] This is the Power Tube Reactor from Korg's Nu:Tekt series. It's a pedal equipped with the next-generation vacuum tube Nutube, designed to replicate the behavior of a vacuum tube amplifier. In terms of effects, it's similar to a compressor. Turning up the TubeGain knob provides a nice distortion. I think it's good to use it like a preamp. Please note that even if you connect this to a solid-state amp like a JC-120, it won't become a vacuum tube amp. It's just a pedal that simulates the compression feel of a vacuum tube amp. Please consider this opportunity. [Condition] There are other paint surface damages and minor scratches due to use. [Included Items] Box [Other] It was stored and used in an environment where a cat is kept. Please refrain from purchasing if you have allergies or are sensitive to such things.
