Savannah Dobro
The Guitarchive - The Savannah Dobro is an excellent instrument. These instruments are well-known for their use in country and blues music. Unlike traditional resonators, which are made of metal, this Savannah Dobro is made from Spruce and Mahogany (with a Rosewood fretboard), providing amazing projection and volume.
You can demo instruments like this at The Local Pickup guitar showroom in Rock Hill, SC.
