The Yellow Flex Oval uses 18-gauge oxygen free copper conductors woven in the oval design Analysis Plus is known for. One of the more interesting aspects of the Yellow Flex Oval cable is that it is a balanced design instead of a coaxial design like most (all?) other guitar cables. It also uses a Teflon dielectric, which I haven't see used in a guitar cable before.

On their Yellow Flex Oval web page, Analysis Plus says, "If you can't hear the difference you don't need one!"

The cable is made in the USA, the connectors are made in the USA, the packaging is designed and made in the USA, the catalog and all paper are printed in the USA.
