The Hagstrom 39 was an early tube-based amplifier from the Swedish manufacturer, dating to the company's initial foray into amplifier production in the late 1950s. It delivered a warm, clean tone through a modest tube complement suitable for jazz, country, and early rock and roll playing styles. As one of Hagstrom's earlier amp designs, the model 39 reflects the period's prevailing circuit conventions adapted for the budget-conscious European market. It is a historically interesting piece as part of Sweden's postwar electric music equipment industry.
