The clear, woody tones singing from the sound hole of an Auditorium-size acoustic guitar with mahogany back and sides and topped with Sitka spruce makes beautiful music indeed. The Blueridge BR-143 is just such an instrument. On paper, the BR-143 appears to be quite similar to the celebrated Martin 000-18. You know what? They actually are quite similar, with perhaps the biggest difference between them being the expense required to own a 000-18 compared to the amazingly affordable price of the BR-143.
