The Agent 13 is the Swiss Army Knife of fuzz! Soulful and subtle, or seriously twisted and textured, the Agent 13 does it all! Equipped with a select set of hand tuned silicon transistors, a 3-way tone toggle, and a wicked, wide-range bias knob, finding your personal sound is just a few twists away. Whether you are chasing a distinctly vintage flavor of fuzz or a monstrously modern wall of sound the Agent 13 has you covered. It can even self-oscillate at maximum fuzz settings turning the Agent 13 into an instrument in and of itself. If versatility and unique character is what you're after than look no further.
