## Questions & Answers

**Q: Is there a full set of 6 strings in each pack and long enough for full size guitar?**
A: See the product information, this will answer your query: http://www.amazon.co.uk/Martin-M170-Acoustic-Guitar-Strings/dp/B0002CZST4/ref=cm_cd_al_qh_dp_t

**Q: are they nylons or steels?**
A: Hi there. They are steel core with a bronze wound cover on 3rd (g) to 6th string, I think, if they follow same pattern as the light ones I buy (red packet), or just possibly 4th (d) to 6th string. A wound 3rd is preferable for fine tuning but not so good for bending. Martin strings are an excellent product, especially at the price quoted. PWN

**Q: What's the difference between cutom light, extra light, light and medium? I'm not sure which one to choose...**
A: Strings are also measured in gauges so 10 11 12or 13 so extra light is 10 custom light is 11 light is 12 and medium is 13 ... But if your a beginner or not playin long I would suggest 11 or custom light .. Should be easier on the fingers regards Cadno

**Q: i use middle strings they hurt my fingers and i muting the strings , how would i improve it , getting extra light strings?**
A: Hi     I have used normal strings and yes they do hurt, now I use light strings or extra light strings and I love them, they are easer on the finger and they sound good to, the ones I like are Elixir Acoustic light 012-053 nanoweb ultra thin coating with anti-rust plane steels. not cheap but good and they last  along time, hope this helps.
