## Questions & Answers

**Q: What would be the downside of putting these strings on an old classical guitar I bought for $25. Would it cause the neck to bow?**
A: Your guitar will be damaged on a classical with steel strings. Classical guitars necks are not built for steel they are built for nylon strings. Your neck will bow and warp

**Q: Are the first 3 strings nylon?**
A: No, they are plain steel as in other acoustic sets. Nylon would only be found on classical sets.

**Q: What would be the best string size to use on a used acoustic guitar to be played by a 9 year old boy?**
A: The lighter the guage...the easier to bend.
The easier to bend...the harder to control.
Since its an acoustic guitar, i would start with 10's ...try .10 to .46. Thats a pretty standard guage. 
He should be able to tell if he would like a smaller guage in which case go to 9's. 
Better yet....take him to a guitar shop and let him try some different guage strings. 
If hes just strumming, he may like the 10's.  When hes ready for more sophisticated play, and until his hands get larger and stronger,  he may need the 9's.  Happy playing!

**Q: Can I put nylon strings on a guitar that use to have metal?**
A: You can. You will need to do a neck adjustment to makeup for the lower tension. These strings are metal that the question was asked under.
