Hagstrom guitar 1966 guitar catalog, page 3. This page highlights some of the great features of mid-1960s Hagstrom guitars. Hagstrom's were pretty playable guitars with good necks - largely due to the H expander-stretcher truss rod, as detailed on the previous page. The central image below demonstrates the "world's fastest playing neck", and was actually the cover image of the previous Merson-produced Hagstrom catalog, from earlier in 1966. The text also describes the Hagstrom micro-matic bridge, in-motion vibrato, electro-sound pickups, and royal-tone strings.
You must let your fingers literally fly up and down this revolutionary neck ...for fast fingering action ... for smoother, easier playing along the entire fingerboard ...for the lowest string action and for the ONLY GUITAR AND BASS NECK THAT STAYS IN PERFECT ALIGNMENT ... a rhythmic miracle from HAGSTROM
The guitar shown is a newer version of the F-200 (see page 7) with switches mounted directly onto the scratchplate. this model was known as the Hagstrom II, or H-II outside the USA.
