## Questions & Answers

**Q: Why is the diam. stated as 0.305"/.77mm here when on the original set of 6 packet the D/4th string is specified as being 0.029"/0.74mm?**
A: There are 3 types of 'blue' classical strings. High tension,  is the 29/74 the classical is 305/77. There is also an imperial string which have different treble strings. Hope this helps

**Q: Are the treble nylon strings a rectified finish? If no, which sets have the rectified finish?**
A: To the best of my knowledge all the range spot clear nylon trebles. They have a carbon fibre range but the sets with "red" in the names have warmer tones.

**Q: are the actual strings black (of course I'me referring only to the first three plastic ones). Or is it just the cover black?**
A: Hello. No, the strings are not black, the winding is silver coloured.  If you have any other questions please feel free to ask the acoustic musical instrument specialists Hobgoblin Music

**Q: Does the pack include 3 nylon and 3 steel strings? Its for a 3/4 acoustic for a child**
A: Hello , this set contains 3 steel and 3 nylon strings . You will need all steel for an acoustic guitar .Regards .
