  • Backs and Sides

    Our bookmatched back and side sets are hand matched for color and grain.The woods we offer are unique and hand selected to combine the finest tonal qualities available, with stunning visual beauty. Available in three sizes: classical, steel string, and jumbo.


    The back and sides contribute far less than the soundboard to a guitar?s sound, but their composition is nonetheless important. The wood used to form the back and sides of an acoustic guitar does a lot more than simply look good and create an enclosure. Even within a species, no two pieces of wood are exactly alike. The inherent tonal properties of different woods play their part in filtering and amplifying the sound that resonates from the soundboard at the front. The combinations of woods, therefore need to be considered carefully when they are paired up. It is for this reason that acoustic guitars frequently feature different woods on the back and sides than they do on the top.??

  • Binding

    Bindings and purfling are commonly made of either wood or plastic.

    Many people think that binding is simply a decorative feature, something to dress up the guitar. Binding definitely does do that, but it has a more important function? protects the delicate and vulnerable edges of the top and back of the body that might occur during a guitar's life.

    Most guitars get bumped at least a few times, especially around the edges of the body. A hard bump may crack or chip the finish. If there is no binding around the body, the cracked or worn out finish will then leave that part of the top or back exposed to the air, releasing and absorbing moisture 5 to 10 times faster at the end grain. This rapid moisture loss can result in devastating cracks. Having binding around the body helps to seal the end grain and decreases the chances of developing a crack in the top or back.

    The choice of wood is a matter of taste but should match the overall design of the instrument. Beautiful hardwood bindings are a natural accent preferred by many luthiers.

    Each unbent binding blank is approximately 0.167" thick, 1.6-2" tall and 29-33" long (750-850 x 40-50 x 4 mm).

  • Bridge Blanks

    A bridge is a device for supporting the strings on a stringed instrument. It transmits the vibration of those strings to the? soundboard?in order to transfer the sound to the surrounding air. ?Bridges are most commonly a single piece of wood that fits between the strings and the surface of the soundboard. ?We?carry several?bridge blanks that could be used for guitars, mandolins and violins.

  • Head Plates

    Whatever you choose to call them?headplates, headstock overlays, headstock veneers, peghead veneers or faceplates, the headplate finishes off your hard work on the neck. They cover the top of the peg head and provide a beautiful canvas to display your logo and craftsmanship. While they are mostly chosen for aesthetic reasons, they do provide reinforcement to the scarf joint. We stock headplates to match most of our back and side sets. When you buy any of our headplates and back and side sets on the same order, we will try our best to match the wood in that order. As with all of our woods, please contact us if you want to see your headplate before shipping or have any special requirements.

  • Top Sets

    Top Sets (soudboards) are hand "book-matched" in order?to assure consistency and visual appeal and are available in three sizes: Classical, Steel-String, and Jumbo (not as common).

    The "soundboard" is the top of an?acoustic guitar?and plays the most critical role in determining the overall tone and projection qualities of the instrument. Spruce has historically been the wood of choice for acoustic flat-top guitar soundboards. However, Redwoods and Cedar are commonly used in soundboards?by?guitar-makers?with great success.

    The following is a summary of woods commonly used in soundboards, and the characteristics of each:
    • Spruce:?Crisp high end. Big bottom-end. Lots of volume.
    • Cedar/Redwood:?Brilliant, "bell-like" tone.
