Well to state the obvious I fell in love with this little wooden drum. The simplicity of the design understates the different tonal qualities you get from the wood used giving each cajon a unique resonating sound. SLAPBOX makes it a point to only by use natural oils, paints & stains. This brings out the beautiful natural featured grain of the plywood and retains the tonal qualities of the wood to enhance the deep resonating base. We choose not use polyurethane products as they act like a rubber glove over the wood restricting the tonal quality as nature meant it for you to hear. All of our cajons are handmade from Russian Birch Plywood B/BB grade. Beautifull featured grain throughout and simply divine to work with.
