Electric upright bass, ARIA SWB-LITE sp. In addition to the belly rest parts and instruction manual, a soft case and stand are also included in the set. It is possible to create sounds by mixing the pickup and piezo. I tried playing it just before listing, and all the knobs worked, but there seems to be some crackling in the line jack. The appearance shows signs of aging, so please check the photos, but there is one noticeable scratch on one side. I think this is the perfect model for beginners of upright bass, so how about it if you are interested?
