?Gitaar

::ABOUT
?Gitaar a walkman playable like a guitar, maybe inspired by Petr Válek's guitars? it is very simple, the idea is that you put in a tone of a guitar, looped recorded on a cassette, or a tape loop. Any sound will do but it works best if it is in a similar pitch. What is a also nice is if it is just a guitar playing some tones and the you change the tones.
When you first press the "let audio out momentary button" there will be a click, because the audio levels need to get matched from the guitar and what you have connected to it. After that the click is almost gone, it can come back when you don't use the button. For say 10 minutes or so (I have not tested this but it might be).
