I purchased this new last month and confirmed that it produced sound. I am selling it to organize my equipment. I noticed a thin scratch-like mark on the SUSTAIN knob during the photo shoot, so please check the 7th photo. The BLUE model is a model that tunes the original RED-only Ram and Coke to a unique and more melting sound based on my own sensibilities. It has a unique characteristic in the mid-range, making it compatible with songs with roaring sounds, shoegazer, ambient, and even pop sounds, resulting in a modern sound. This is a recommended unit for those who are tired of standard muff-type pedals or those who don't want to be the same as others. This time, I asked "Sensei Hikari Matsuda" to create the illustration, resulting in a cute yet cool design. The enclosure is made of stainless steel hairline and a leather-like sheet to further emphasize its "character." Furthermore, I have added controls this time: The first is the Gate control, and the second is the ToneShift switch, which are located on the jack surface of the enclosure. There is almost no sign of use. The original box and instruction manual are included.
