Retro Instruments Doublewide II ・Tube Compressor ・Wide range of attack and release times ・Premium quality Cinemag input/output transformers ・Improved tube characteristics, S/N ratio, and frequency response compared to the previous model ・Stereo link switch for use with two units In my subjective opinion, it's in good condition, but since it's a used item, please refrain from purchasing if you are looking for a new one. The accessories are all that are shown in the photos. Regarding the screw in the lower right corner of photo 4, it was missing from the time of purchase. It corresponds to the screw hole in the upper left of photo 9, but since there is no screw receiver on the chassis, it is believed to have been originally absent. No returns or exchanges except for initial defects such as no sound.
