La Bella Electric Guitar Stainless Steel Flatwound 12-String 11-52 Gauge
The official line from La Bella:
“La Bella stainless steel Jazz Flats® were developed by the best jazz guitarists in the world. Each string is hand wound and polished by our artisans in New York, resulting in a super smooth surface eliminating finger noise and squeaks. Optimized with a high magnetic content for increased electronic output, La Bella Jazz Flats® have a very bright sound and long playing life. We’ve recently improved our string construction to fit more models, and prevent overtones.”
