This 1969 Kustom 100-2 is a highly original example of one of the most recognizable American solid-state amplifiers of the late 1960s. Finished in its iconic silver tuck-and-roll covering, it retains its original cabinet, grille cloth, hardware, electronics, and a pair of original Jensen 12-inch speakers, making it a remarkably authentic survivor with no functional modifications noted. The amplifier has been thoroughly evaluated by Blue Note Music and exhibits the honest cosmetic wear expected of a working vintage amp, including moderate cabinet wear and chassis corrosion, while maintaining 100% originality and strong structural integrity. With its unmistakable vintage appearance, warm clean tones, and unmistakable Kustom character, this 2x12 Head and Cabinet is an excellent choice for players, collectors, and enthusiasts seeking a genuine piece of American amplifier history that is ready to be enjoyed today.
