## Questions & Answers

**Q: How would you measure 4/64 and 6/64 with this tool? Would it be possible?**
A: It has a spot for measuring 64th's on the bottom left on the front side, but it only goes to 48/64, which should certainly be enough for measuring string height.

**Q: Does this item come with instructions, and is it made of steel?**
A: No instructions.  It is essentially just a ruler.  But the size, shape and multi-denominations make it especially designed for guitar setups.  It is made of high-quality (stainless?) steel with black etchings.

**Q: I tend to use 32nds for setting up string heights on my bass.  How do you use that area when it's in the middle of the rule?**
A: You use the 64ths. two 64ths = one 32nd. Either that or saw a hole through your bass and stick the tool through

**Q: where is this item made**
A: No idea. Bought this for my boyfriend it was 1/2 the price of the one offered by Stewart MacDonald.  He loves it--- perfect gauging string height
