Here is what Echopark had to say about this MILKY BOYYYYYY:
"Influenced by Mosrite's rarely seen legindary 'Fuzzrite' produced in limited numbers threw the mid 1960's.. ?The F1 circuit is designed to satisfy the purely devoted vintage fuzz freak and the seeker of new sonic territories alike. The 'Level' sets the dry to effect volume of the F1, while the 'Blend' control blends the first stage of germanium transistor into the second stage of Germanium transistor creating everything from a subtle fizzle, big fat hairy boost. Harmonic flutter or solid milky walls won't be sacrificed when using the instruments volume control or adjust the pedal volume. Leaded solder on solid boards with individually measured/ tested discreet components. Solid mil- spec construction and care.? True bypass switching. Made in America"
