This is the ISP TECHNOLOGIES HUM EXTRACTOR + DECIMATOR G PEDAL noise reduction pedal. Please refer to the following for product specifications: https://www.isptechnologies.com/portfolio/hum-extractor-decimator-g-pedal/ I bought this a few years ago on a whim, but I never used it and it's been sitting in a closet, so I'm putting it up for sale. I was planning to put it on an effects board, so a spacer for height adjustment is attached with strong adhesive tape. I'm selling it as is because the paint might come off if I peel it off. It seems to be selling for around 100,000 yen on ○mazon right now. It seems to be able to eliminate noise almost completely, but I don't know because I never used it after I bought it. There are no Japanese instructions, and there's not much information on YouTube, so please refrain from purchasing unless you can figure it out yourself. No claims and no returns. In my subjective opinion, there are no scratches or stains. Please check the photos for details. Includes original box, instruction manual, and AC adapter. This pedal requires an AC9V (not DC9V) power supply, so a 100V -> 9V adapter is included. I will ship via Rakuraku Mercari. I may be able to offer a discount within a reasonable range. Please contact me in the comments. I will delete comments and block users who request discounts that are clearly not reasonable. No claims and no returns.
