Kopp L-02. Mahogany back and sides, Adirondack top, Ivoroid binding and bridge pins, Rosewood fingerboard, Mahogany neck, Waverly tuning machines. A superb little blues machine. Kevin Kopp builds superlative guitars that hark back to the pre-1950 Gibson aesthetic.He builds them by hand one at a time. The small body shape lends itself perfectly to finger styles and the presence and poise of these remarkable guitars must be felt and heard to be appreciated. Alternately, having experience with vintage classics informs the player of what to expect from a Kopp.
