With acoustic guitars, the front of the guitar body is the primary canvas. Justin is fond of collage, and old wallpaper designs are some of his favorite materials. Several of his acoustic guitars feature remixed, collaged wallpaper almost exclusively. Others use prints of art and photography and other collected materials. Because the sound of an acoustic guitar depends largely upon the top, he makes every effort to keep layering of materials to a minimum. This is accomplished by "nesting" the collaged elements into each other so that they fit together like puzzle pieces, without overlapping. He finishes each collaged guitar with numerous coats of sealer so they will withstand normal usage and can be cleaned with a damp cloth.
Guitars covered with embossed metals or detailed ink designs add yet another dimension to the work.
With electric guitars, he removes the finish, changes the shape and softens the feel of the guitar - removing hard angles and creating contours that mass-produced instruments rarely exhibit. His favorite materials for accentuating electric guitars are inks and a woodburning tool.
