XL Chromes are our warmest, mellowest electric guitar strings. Beloved by jazz guitarists, as well as blues legends like Gary Clark Jr., these flat wound strings provide the smoothest feel and warmest tone, while allowing movement across the fretboard with no finger noise. Made with a high carbon steel core, Chromes’ stainless steel flattened ribbon wire is expertly wound onto a series of interlocking under-windings, then precisely polished for unparalleled smoothness and a sound which blends beautifully into any mix. This 12-52 Light set adds some additional tension over Jazz and Extra Light flat wound gauges, for a slightly fuller tone. D'Addario Chromes are wound with flattened stainless steel ribbon wire which is polished to an incredibly smooth surface. Chromes deliver a distinctive damped, but tone-rich sound that only flatwounds can produce. D'Addario Chromes are the world's most popular flatwound strings. XL Chromes are a flat wound electric guitar string, which provide a mellower tone than round wound strings. Chromes’ stainless steel flattened ribbon wrap wire is precisely polished for unparalleled smoothness and the warmest tone you’ll find from an electric string.
