This is a rare, highly sought-after effect pedal from an American workshop, with a Showa-retro design. Manufactured between 2000 and 2010, it uniquely features a true bypass/buffered bypass switch, which was uncommon at the time. The sound is bright for an analog delay, and is especially recommended for those who like the Maxon AD-900. Due to the prevention of parts swapping, all sales are final, with no returns accepted.
