【Product Description】 This is the Maxon ROD880 Real Overdrive, a famous model that incorporates a real vacuum tube. It features a warm and sticky overdrive sound unique to vacuum tubes. With its 3-band EQ (BASS, MID BOOST, TREBLE), it's possible to create a very wide range of sounds, from delicate clean tones to thick and intense distortion. I used it because Hotei used it. 【Condition of the Product】 ・Operation confirmed. There is some scratchiness in the gain and master knobs. ・The exterior has minor scratches from use, but there is no major damage and it is in relatively clean condition. ・This unit is DC10V, but a rare "genuine AC adapter (AC210)" is included, so you can use it immediately. 【Included Items】 ・Effector body ・Genuine AC adapter 【Shipping】 We will carefully pack it with cushioning material (bubble wrap) and ship it quickly. If you are looking for real distortion with a vacuum tube, how about this opportunity? Thank you.
