Ceramic capacitor 0.01uF KCK, made in Japan in 1966. When used for tone control on a bridge pickup, it creates a wah-like, nasal tone when the tone is rolled off, as if the wah pedal is half-way engaged. It sounds great with single-coils, P-90s, and humbuckers. I have plenty in stock, so please message me if you need more than one.
