The k-73 is very transparent. caps lean slightly toward the brighter end of the frequency range, so they do clean up some mud. They offer 600 vdc and 5% tolerance,  perfect for guitar as well as tube pre-amps or pro audio projects. Tight Tolerances are hermetically sealed .Glass bodies within a strong metal cases and long leads . Russian military capacitors are a superb tone upgrade for your electric guitar, Tube amp, Wah pedal or stomp-box. K73s,vintage PETP Poly Film caps. Perfect small size for guitar cavities (approx. 23/32" long and 9/32" wide) and a great sounding alternative to higher priced Paper In Oil (PIO) caps.
