Hagstrom first began building guitars and basses in 1957 and continued through 1983. The brand was reintroduced as an overseas product in 2004. For a complete history on Electric Guitars, refer to the Blue Book of Electric Guitars.
In the late 1950s or early 1960s, Hagstrom started to produce tube guitar amplifiers, and it is also rumored that Hagstrom built amps for Guild. Hagstrom continued to produce tube and solid-state amplifiers throughout the 1960s and into the 1970s. Even though Hagstrom produced a number of amplifiers, many of them never made it to the U.S. and very few are found in the used marketplace. This makes used evaluating very difficult, and at this point we do not have a solid pricing scheme. Some popular models seem to be the GA-225 and the briefcase amp, which are both pictured. Any further information on Hagstrom amplifiers can be submitted directly to Blue Book Publications. Information courtesy Kwinn Kastrosky, Yesterday's Guitars.
