This is another Paul Reed Smith-ism. He uses it to describe the distinctive voicing of the shorter scale (24 1/2-inch) PRS guitars, such as the PRS Santana and the new Singlecut SC245. According to Smith, these guitars have more of a defined high midrange, but without a strident high end. This is the classic “Santana tone” heard on hundreds of recordings made using the PRS Santana model, including the mega-hit “Smooth.”
