Cottonwood is an excellent alternative to traditional double bass back materials, offering both distinct advantages and remarkable qualities. It is not only more affordable compared to other woods, but it is also incredibly easy to work with, making it a popular choice among luthiers. This particular piece features a carefully crafted four-piece flat back with a ribs blank specifically designed for a double bass.

The accompanying photos showcase the actual back, providing a clear view of its unique characteristics. The colour throughout the piece is a beautiful, warm hue that is common to Cottonwood, enhancing its overall aesthetic appeal. Additionally, you may notice several bug trails adorning the surface—these are typically considered workable and add to the charm and individuality of the wood. The shallow knot in the ribs blank has been noted and should allow for enough material
