Gustaf Jonason

Swedish recording and mastering engineer.
Until 1923 Jonason worked as engineer for Skandia Record in Sundbyberg. After Skandia was taken over by Lindström, he made the Scandinavian and Baltic Odeon recordings, as well as the Scandinavian recordings for Parlophon, Homocord and Columbia, and from 1932 onwards, for the Scandinavian HMV.

He signed his acoustic recordings with “J” in the run-outs and his electrical titles (can be identified by £ or ℒ in a circle) with “JS”.
