This cherryburst Rangemaster Model 109R Goya guitar was made by the “Polverini Brothers” of Italy (not by EKO as previously thought) in the late 1960’s. The multi control panels that were common with Italian instruments from that era, include a master volume next to three tone options, low, medium and high. The upper controls are for pickup selection, as the pickups are split into 3+3 x 2. So the controls are: 1+2, 1+4, 2+3, 3+4, off. Pretty cool!
