The credits on https://musicbrainz.org/release/df44641b-7e90-463d-9697-7e60c0aeab5c say that Michael Manring plays the "Electric Bass" and the "Electric Bass [fretless]" at least according to https://www.discogs.com/release/6905495 . I think Fretless Bass is not the same as Electric Fretless Bass, so I'm requesting to add it as an instrument.
