This was my grandfather’s amplifier which he played the fiddle through. He bought it new. He and I are the only owners.
This 1950s 1x10 Rickenbacker M-11 is equipped with 6V6s, 6SJ7, 6N7 and 5Y3 vacuum tubes. It has one volume and one tone knob. Cranking the volume knob to about halfway introduces some haptic feedback. It is sold in as-is vintage condition as amplifiers of its age often need service and upkeep.
