Excellent cosmetic shape with a striking blue sparkle finish that catches the light beautifully. Only minor wear—tiny scrapes and edge scuffs around the corners consistent with careful use. All knobs, jacks, and switches are intact and responsive. A clean, well-preserved example of this early-2000s BOSS classic.
