Goya guitars had been made in Sweden by Levin and Hagstrom for many years before they launched the new Rangemaster series of electrics in 1966. These were a series of Italian-built semi-acoustic and solid body electrics, each equipped with split coil pickups giving an improved tonal range (hence the Rangmaster name). There were a number of different models, with different body shapes, body woods and finishes. The guitar illustrated is the Rangemaster 109S in Sunburst finish.
This baseball-inspired advert, with it's baseball-derived puns was squarely aimed at the US guitar-buying market, and appeared in Downbeat magazine in mid 1966.
Here's the pitch. Goya have developed a system of split pickups that revolutionize the electric guitar. 4 split pickups out of the usual 2. On one chord you get the total sound range. From the highest treble to the lowest bass.
