This is a reissue model from 1991, a revival of the original RAT's legendary design. It features the popular large box enclosure and the Motorola LM308N chip, the heart of the distortion. The back cover has a "The RAT" logo sticker and serial number (RT-167759), with **Made in U.S.A.** written on it. Everything is in its original condition. [Operation] No scratchiness, overall good condition. Each knob and footswitch have been confirmed to operate normally. [Appearance] There are some minor scratches and small marks from use, but it's in quite good condition considering its age. It has a unique sound, thick and gritty, unlike current models. This is a valuable item for collectors. ※ I'm personally fond of this unit, so I'm still hesitant to list it for sale at the moment. Therefore, please understand that the price is set a bit higher. ※ Please consider this item with the understanding of the characteristics of old equipment. If you have any questions, please feel free to ask before purchasing. ※ It will be carefully shipped with cushioning material and waterproof packaging.
