The WINE stomp-box is a practical and sturdy wooden wine case, which when connected to an amplifier transforms into a powerful stomp.box that emulates the sound of a bass drum. It can be opened and therefore very useful for containing your accessories but just connect it to a musical instrument amplifier and tap the tempo with your foot to transform it into a useful and simple rhythmic accompaniment for your One Man Band concerts. No power batteries required. The dimensions are 35x30x10 cm You can find the demo on my YouTube channel at the following https://www.youtube.com/watch?v=ZzdahYDEfVoaddress: Or visit my Facebook page Robert Matteacci Cigar Box Guitar
