The Bentobox is a DIY guitar/audio amplifier. It works great with electric guitars as well as with other audio devices such as smartphones, laptops and of course our cool Lunchbox synthesizer.
The knob on top lets you control the amount of gain, allowing you to get some loud and crispy sounds.
The bentobox comes as a DIY kit that you can solder yourself using the thorough manual available on this page.
