Review: De momento no he cambiado desde hace mucho tiempo de modelo de cuerdas. Me encanta su sonido, y sobre todo su facilidad de tocar, notándose mas blandas al tacto que el resto, lo que facilita notablemente tocar la guitarra cuando no tienes tanta fuerza o eres aficionado. Además, de momento no he tenido ninguna rotura, las limpio siempre después de tocar y les aplico dunlop 65 de vez en cuando para lubricarlas, y ningún problema. Duran mucho, las suelo cambiar por tiempo, no por desgaste. Review: Marvelous. Bright tone, durable. ## Features - Fantastic quality strings - One complete set of strings - Custom light gauge (.012 - .054) - 92/8 phosphor bronze - Packaging May Vary ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0029SYO0S | | Brand Name | Martin | | Coating Description | Bronze plated | | Color | Phosphor Bronze | | Country of Origin | Mexico | | Customer Reviews | 4.6 4.6 out of 5 stars (744) | | Finish Type | Bronze Plated | | Global Trade Identification Number | 00729789390286, 00729789558013 | | Instrument | Acoustic Guitar | | Item Type Name | Acoustic Guitar Case | | Item Weight | 0.05 Pounds | | Manufacturer | Martin | | Manufacturer Part Number | 41Y19MA540FX | | Material Type | Phosphor Bronze | | Model Name | MA540FX | | Model Number | MA540FX | | Recommended Uses For Product | General use with acoustic guitars for various playing styles | | String Gauge | .012 | | String Material Type | Bronze | | UPC | 729789390286 729789558013 | ## Product Details - **Brand:** Martin - **Colour:** Phosphor Bronze - **Instrument:** Acoustic Guitar - **String gauge:** .012 - **String material type:** Bronze ## Images ![Martin MA540FX FX Flexible Core 92/8 Phosphor Bronze Acoustic Guitar Strings - Zinc Flashed Inner Core (Custom/Light.012 - .054) - Image 1](https://m.media-amazon.com/images/I/61CHqTfGTgL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by G***E on 1 October 2024* De momento no he cambiado desde hace mucho tiempo de modelo de cuerdas.
