This is a custom-made Marshall Supa Fuzz replica, commissioned directly from Yusuke Watanabe of Organic Sounds. The appearance is also very close to the Supa Fuzz. I believe it was made about 7 years ago. Since it has almost the same circuit board as the Tone Bender mk2, please consider the sound to be similar to the Tone Bender series. I apologize that I don't know the details of the circuit board and parts, but it basically follows the specifications of the Supa Fuzz. As a completely custom-made item, this is a valuable, one-of-a-kind piece. Operation has been confirmed. The only included accessory is the 9v battery used for the operation check. (It seems to be incompatible with alkaline batteries, so please use the included battery to test the sound first.) It will be packed in cardboard and shipped. Basically, no returns or cancellations are accepted. Fuzz maniacs, please consider this item. Thank you.
