Solid Sitka Spruce top, solid Mahogany back and sides, affordable price and that "Gibson" tone make the Hummingbird Pro a great guitar. Though the Hummingbird Pro differs from the standard Hummingbird in scale length (Pro 25 1/2" Std 24 3/4"), body size (Pro is considered as "small square shoulder"), it delivers that dry, full, woody sound which the Hummingbird is so famous for. When comparing the two, we felt that the Pro was a bit more brilliant with less bottom end. The sound of the Pro is clear and very solid, it's a great guitar, as we said already. The pickup system which it is equipped with, the L.R. Baggs Element system, is simple and efficient. It is the plug and play type, with the joy of sounding natural and balanced on every stage.
