MartinMA130FX Strings SP Flexible Core - Silk & Phosphor Custom (11-47)

MartinMA130FX Strings SP Flexible Core - Silk & Phosphor Custom (11-47)

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?

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.

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?

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?

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
