Thank you for viewing this product. I used it a bit after purchasing it new, but I am selling it because I purchased a multi-effects unit with a looper. Please rest assured that the operation has been confirmed. Description below: Loop station with stereo input/output. Supports up to 3 hours of recording and 99 phrase memories. The twin-pedal type RC-30 has significantly expanded the recording time from the previous model's 16 minutes to 3 hours. Up to 99 types of loop phrases can be stored in the main unit, allowing you to perform with more phrases and longer phrases without worrying about recording time. It also supports stereo input/output, allowing connection with stereo effects. The RC-30 is also equipped with an XLR microphone input, so it can be applied to various instruments such as vocals and percussion, in addition to guitars and basses, for loop performances. There are some signs of use such as minor scratches and dirt, but there are no problems with the operation. - Model name: RC-30 - Type: Dual Track Looper - Functions: Loop effect, Rhythm function - Manufacturer: BOSS ■ External dimensions/Weight Width (W): 173mm Depth (D): 158mm Height (H): 57mm Weight: 1.2Kg ■ Included items Main unit only Manufacturer...BOSS
