The Hagstrom Swede bass, or model HB 903, was only built in small numbers: just 1479 basses shipped between 1971 and 1976. Unlike the current range of Hagstrom guitars, the 1950s-1980s Hagstroms were built in Sweden. This example comes from 1973 and is pretty typical: translucent cherry finish, mahogany body, mahogany neck with an ebony fretboard. It's a really nice bass, beautifully appointed with a very wide tonal range, and a great playing feel. It is relatively heavy though for a mahogany instrument, mostly due to its thick solid body. Very cool bass, and certainly one of the very best basses produced by Hagstrom.
