These are the strings we have on the new Smoothboard guitars. Great sound. Quality strings. If you're playing a fretless with a standard fretless fingerboard and roundwound strings, cut it out! They will eat up your fingerboard! The D'Addario flatwound strings belong on your fretless guitar.
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.
