If you are the long-suffering partner of a guitar player, you'll doubtless have been subjected to years of noise pollution emanating from their general direction. It's obviously in your interests to make sure that their absent-minded noodling is in tune, so look no further for a discreet solution!

In the words of Guitarist magazine, the NS Mini Headstock Tuner is, "very neat, very inconspicuous, very small," which makes it perfect stocking filler fodder alongside the usual array of walnuts and tangerines. When used live, it's also virtually impossible for the audience to see it in situ.
