The La Bella 20PH Jazz Flats are stainless steel flatwound electric guitar strings in heavy gauge (15-56). These are the thickest strings in the Jazz Flats lineup, delivering maximum warmth, volume, and a very firm playing feel. Heavy gauge flatwounds are favored by jazz guitarists who want the deepest, most resonant tone possible, with plenty of resistance for strong chord voicings and controlled vibrato.

Stainless steel flatwound construction provides the smooth, polished playing surface and warm, controlled tone that define the Jazz Flats series. At 15-56, these strings have substantial tension that rewards a firm left hand and produces a big, full sound from archtop and semi-hollow guitars. The smooth surface eliminates finger noise completely, a critical feature for the intimate dynamics of jazz performance. Handcrafted in New York, the 20PH is for the jazz purist who wants the fullest, warmest, most commanding flatwound tone available.
