to be unusually thin. Thus the action can be set lower than guitar necks built with traditional truss rods. Beside their line of instruments Hagström also produced amplifiers, speakers, effects units, guitar strings and mixing consoles, which were used by ABBA on their first world tour. A very small run of lap steels, banjos and mandolins were also built but are rare to come across. In 1962 Albin's son, Karl-Erik Hagström returned from working five years in the US with establishing their Line O guitars. In 1967 he took over as CEO of the company. In their native Sweden, the company became well known not only for selling music hardware, but also for "teach-yourself" books and mail courses on electric guitar, bass, keyboards etc., learning tools that deliberately took in a rock and pop repertory, chord analysis and tuning apart from teaching how to read music. By recognizing the electric guitar as an instrument in its own right, and not just an amped-up version of the acoustic and by accepting the new repertory, Hagström popularized the instrumental skills of the new music outside of the networks associated with rock clubs, and record shops, and at a time when rock music was barely ever being written about from a musical perspective. Production ended for Swedish-made Hagströms in 1983 as the company were outpriced by other major guitar brands that had moved their stock production lines to Asia. Hagström did make some Japanese prototypes; however, they were not pleased with the workmanship and would rather close down the company than cheapen the brand. The interest in the original Hagström brand still has a cult following around the world and a Hagström Festival takes place in Älvdalen, Sweden around the first week of June every year since 2006.
