This is a prototype 66 Fuzz Face created by Mr. Watanabe before he established Organic Sound. I purchased it around 2016 and have kept it carefully. Operation has been confirmed. The serial number is 1/1, and as a result, this product uses many valuable NOS parts, such as wires, pots, jacks, and capacitors. Yusuke Watanabe collected vintage NOS parts used in the original Fuzz Face and created his replica, the Orga Face. The germanium transistor is NKT612. The sound at full gain is indistinguishable from the original, but the bell-like sound when the gain is dialed back is unmatched. I believe this is the best sound among the many clones. Everything in the photos is included.
