is a one Watt small guitar amplifier based on a JFET guitar pre-amp, the Big Muff Pi tone control and the power amplifier. This portable amp is an open hardware project designed by ElectroSmash using only free and open-source tools.
Here is a small guitar/uke that I have crafted. The infilled face of the guitar is constructed of many different types of metal fixing. Together they create a beautiful symmetrical pattern throughout the whole instrument. Who knew nuts and bolts could be so pleasing to the eye. Finished #beautifulguitars
