"For about six years in the 1960s, the Hoshino Gakki company (better known by their most popular brand, Ibanez) produced guitars at their Tama plant in Japan. ... The factory churned out some really kooky designs and this Hy Lo model 2103 is a good representation of the kook factor! The segmented guard is very reminiscent of the early UK Burns guitar design."
