YouTube video Josh Vanjani · 2023-10 — The M600 set fitted to a concert ukulele and played through a sound test

Josh Vanjani plays the M600 set through a sound test, which is the quickest way to hear how fluorocarbon behaves on a concert scale.

Why it matters

Martin has been making ukuleles for over a century, and these are the strings it sells for them. The material is clear fluorocarbon rather than nylon, chosen for tuning stability and a bright, projecting tone, and the range is two sets: M600 for the smaller scales and M620 for tenor. Martin also sells a Polygut Premium line developed with Aquila, for players who want a softer, more gut-like voice from the same maker.

Note

Martin's ukulele sets are clear fluorocarbon. M600 fits soprano and concert, M620 is the tenor set, and those two model numbers are the whole range.
