Vintage Black Cat capacitors. Tested and confirmed working with a tester and guitar; readings are good. .01 600v New Ideal for humbuckers in guitars. Also suitable for other electronic components. Black Cat capacitors are high-quality film capacitors known and popular for their good sound. They are characterized by a crisp, straightforward sound quality, unlike oil capacitors. Cornell Series Compared to Sprague, Cornell has a wider range, extending to higher frequencies, and a bright impression of good sound. I subjectively describe the characteristics of each model below. Black Cat: Standard bite, wide range down to the low frequencies, strong vintage feel. Greenie: Similar to Black Cat, but with a slightly stronger bite and a more undulating sound. Blackie: Similar to Greenie, but with a slightly stronger bite and a wild sound quality. Tiny Chief: Slightly less low-frequency range, strong undulation. Wild sound quality. Popular for heavy and punk genres. Maroon: Similar to Tiny Chief, but with a wider range and stronger undulation. Cub: Standard bite, similar to Black Beauty but with a slightly brighter sound quality.
