This is the Flyingteapot RAT-style distortion REINDEER (RDD-2). Personally, I think it's a more user-friendly distortion than the original RAT, without as much of a strong character. The "Filter" parameter, which can be a bit tricky to use, has been replaced with a Tone control, which is also a user-friendly feature. I think it would also work well with a low gain setting for bass. This is an auction for the unit only. I think this is an effector that is rarely available on the used market. Operation has been confirmed. Used in a pet-free, non-smoking environment. Price is not negotiable. Thank you. #guitar #effector #distortion #RAT #flyingteapot
