Argentine strings are the original strings for Selmer Maccaferri
guitars. The French string maker Savarez was commissioned by Selmer to
design an appropriate string for their guitars.
Argentine strings are comprised of a round steel core with silver
plated copper windings. Most strings today are made with hex cores which
provide greater stability but are also stiffer and not as bright as the
round core Argentine strings.
Django Reinhardt and nearly every other Gypsy guitarist throughout
history has played Argentine strings. Their unique sound and supple feel
has made them the #1 choice for professional jazz manouche guitarists.
In the 80s, Savaerz improved the design of Argentine strings so that
they would last longer. These redesigned strings are called "New
Concept." The originals were so fragile they often had to be changed
every day. Occasionally you will find an old vintage Selmer guitar with a
few packs of the older Argentine strings in the accesories pocket of
the case.
