This is a tool that has its definite pros and cons. It features 6 tubes and 6 brass reeds, one for tuning each string. The overall quality is good, much better built than I thought it would be. This pitch pipe is good for bringing a guitar to AROUND standard tuning. I found that the D was extremely off, though.

Overall, good tool for a musician that just wants something of a reference(high E tube was perfect). If you cannot tune by ear yet, you are better off with an electronic tuner.

The notes are not correct. I mean the "D" is waaayy off. It's good that it's specifically for guitar with E A D G B E, but I guess you get what you pay for. I'm going to buy a better one.

I would say don't waste your money, just go buy a battery operated tuner. I bought this with the thought I would use it as a backup to the tuner I already own, but I realize I wasted money and will just buy another batter operated tuner instead. Don't waste your money.
