I queried Thomann support for a recommended case for a Sandberg (Ida Nielsen) bass, and the SKB44 was recommended. It has the shape of a J- or P-bass, but as the Sandberg bass' body is somewhat smaller, the bass is not secured and firm in this case. Case however fits a Yamaha BB bass nicely, so this is the future use for the case, as the case seems fine, solid and easy to handle.
