The Nerdy Gurdy v6.1 has 2 melody strings (g3 and g4), two drones (c3 and g2) and two trumpet strings (c4 and g3). The latest version has some small but significant improvements over the v6, which has been built by thousands of people from all over the world. These are mostly related to increasing the volume.
The kit contains all the parts that you need to build an instrument (just add glue).
