From D’addario:

For four generations in the USA, the D'Addario family has been committed
to offering the highest quality musician's gear you can buy. The tradition
continues with our D'Addario American Stage Cables.
American Stage Instrument Cables are precision engineered and expertly
assembled in America, in our Farmingdale, NY facility. We begin with a
proprietary, audiophile grade cable manufactured in the USA, featuring
low 28pF/ft capacitance (the tonal sweet spot) and 95% shielding
coverage, allowing your instrument's brilliance, presence, and character
to be transmitted with the utmost transparency. Our exclusive D'Addario
designed, Neutrik® built plugs feature the patented Geo-Tip, ensuring a
secure connection in any instrument, pedal, or amp. Our in-line HelioFused
soldering provides unequaled connection and strength at the solder joints.
These unique engineering and cutting-edge technologies combine to
create a cable that will exceed the most demanding expectations. The gig
is on the line every time you plug in, and we're committed to giving you the
best sounding, most reliable cable available. We guarantee it!
