One of Hagstrom'ss last projects before their Swedish production stopped was a collaboration between their chief guitar designer Per-Åke Olsson and Rutger Gunnarsson, bassist for the Swedish super-group ABBA. This resulted in the Super Swede Bass, which was used by Rutger throughout ABBA's final North American tour in September/October 1979. Only 364 of these basses were produced before Hagstrom ceased guitar production in Sweden, and over the years they've become a sought-after collector's item.
