Review: Martin excellence. - Overnight delivery! Strings sound awesome. Easy to fret. Highly recommend.
Review: Great strings! - D'Addario strings are great! I have their XS Phosphor Bronze on my guitars but tried the Silk n Steel on the mahogany guitars and they are fantastic. Adding mellow tones to the sound. I saw these Silk and Phosphor and had to try them. I put them on a new 0 sized spruce and rosewood guitar. Easy on your fingers, do very well on bending and add just a little brightness to the mellow tone. I have already ordered more.

## Questions & Answers

**Q: My problem is some stings are to stiff and hard to push down on the neck. The ones I have now are hard to push down are these soft or hard strings?**
A: These are great strings, but they are medium gauge strings. For strings that are easier to push down I would recommend Light or Extra Light strings.

**Q: Is the custom gauge set for the silk and phosphorus strings or silk and steel? The selection (custom) and picture are of 2 different products.**
A: The Silk and Steel are a nickel plated string- softer to the touch. The silk and phosphorus sound more like a acoustic. The nickel you will loose some volume. More like a electric string

**Q: Are these correct for my martin 12 string dm-12 acoustic guitar?**
A: i do not have a 12 string,but martin strings is all i use

**Q: what is what is the difference in "silk & phosphor" and "phosphor bronze" strings? Which One has warmer and deeper lows?**
A: There is No difference except- the silk have been made a little softer to the touch. Like-slightly sanded off, they are warmer and deeper. They do not last quite as long but worth it to my ear. I’ve played for 25 years- To get a warmer sound you need a Nylon pick. I love the Dunlap 1.38mm Jazz pick. Then I take some 2000 grit sand paper ( you have to buy at auto parts store) and Buff both sides and edge of pointing end that hits the string. Trust me. Makes it Creamy warm. Sometimes works better than other times. But I love it! So all you hear is the Note instead of all the bright metallic overtones. Good luck

### ⭐⭐⭐⭐⭐ Martin excellence.

Overnight delivery! Strings sound awesome. Easy to fret. Highly recommend.

### ⭐⭐⭐⭐⭐ Great strings!

### ⭐⭐⭐⭐⭐ Bel suono e bella estetica, ottima suonabilità
*by F***O on 17 September 2022*

Le ho prese inizialmente per la chitarra Eko di mia figlia, 13 anni, che già suona ma con corde bronzo regolari fa un po' fatica. Ora le ho prese anche per la mia Cort. Sono esteticamente molto belle e ben fatte. Il suono è pieno e ha profondità ed effettivamente sono molto più flessibili al bending. Creano meno tensione senza però perdere volume o tonalità. Non sono morbide come le silk and steel Le silk and steel hanno una morbidezza estrema e un touch confortevole ma che testituiscono anche un suono molto dolce (mellow) e sono di colore argento invece che ambrato. Non credo ci sia paragone con le silk and steel in tema di morbidezza, ma hanno certamente una buona suonabilità rispetto alle bronzo "normali". Se si viene da corde con maggiore tensione, sarà necessario regolare il truss rod per dare relief al manico. Operazione facile, basta inserire la chiave nell'innesto dentro la buca e fare 1/4 o 1/2 giro antiorario, ed eventualmente ripetere l'operazione il giorno dopo se non basta. Il manico è di legno e ha bisogno di alcune ore per assestarsi all trazione del truss rod. Quindi veritieri i dati dichiarati sulla tensione. Quindi, ottime per allentare la tensione sul manico e suonare più facilmente la chitarra, anche se rappresentano comunque una soluzione intermedia tra le bronzo e le silk and steel.
