Stemfluit voor gitaar, plastic

There are now all kinds of advanced tools to tune your guitar, but the most simple and most effective way is still the voice flute. The voice flute sounds and acts a bit like a harmonica, though there are few songs that Toots Thielemans can play on it. The BPP-6 adds an E-A-D-G-B and a high E to the show, corresponding to the six strings of the guitar.
