This is a fuzz pedal from "A.Y.A tokyo japan," a domestic handmade effector brand founded by Makoto Kawai as a unique brand of the famous Japanese shop f-suger. It's a masterpiece made in Nakano, Tokyo, with meticulous attention to detail in every component, from the wiring and resistors to the solder. As the model name "BM (=BIGMUFF) 80" indicates, it delivers the sound of an 80s Big Muff. Contrary to its gentle and cute design reminiscent of a Japanese summer, it produces a rather wild sound. The current model was renewed in 2024, but according to Mr. Kawai, "the appearance is almost unchanged, but the contents and sound are completely different," so you can experience a rare fuzz sound that is different from the current model. I purchased it used last year. Operation has been confirmed with an adapter. All knobs function correctly. This is a sale of the unit only, without the box. I would love to pass it on to someone who will use it a lot, since I haven't used it much. - Model Name: BM-FUZZ 80 - Brand: AYA tokyo japan - Manufacturing Date: April 11, 2007 - Manufacturer: Makoto Kawai Type...Electric Guitar fuzz big muff Big Muff
