This is a Fuzz Face-style pedal handmade in Spain. Unlike current models, it is a battery-only power type, and given that it is a two-digit serial number, it is likely an early model. The gain is quite high, and it was able to achieve sufficient distortion even with a Fender amp set to clean. This particular unit has a thin, hand-painted lacquer finish, so there are some signs of peeling, but it is in good working order. I believe it will develop a more atmospheric appearance as you use it, so if you are interested, please consider it at this opportunity. The box and instruction manual are also included. Thank you for your consideration.
