This is the Roland (BOSS) sampler SP-303. It is a sampler that is still popular even after the release of the successor Roland SP 404. This time, I exhibited it for the purpose of organizing the equipment. It is an exhibition of the main body and the genuine adapter shown in the photo. There is no original box and instruction manual. The instruction manual is not attached, but it can be obtained from the Internet. Please search in the BOSS SP-303 instruction manual. (It seems that the listing may be deleted if you enter the URL, so please check for yourself.) Turn on the power, and the operation of Line in.Line out.MIC in.PHONE out. Has been confirmed, and sampling has also been tested. Sound was also produced with eight pads. I didn't have any volume control, so I don't think there is any.
