This is a Harmony H-802 electric guitar in a sunburst finish.
This model was manufactured in Japan during the late 1970s and 1980s.
It typically features a solid body, two humbucker pickups, and unique sliding switches to control them.
While originally budget-friendly, these guitars are now collected for their distinct "raunchy" tone, often compared to a P90 pickup. [1, 2, 3, 4, 5]
