This is my final instrument and I made it with plywood, Whey protein
bottle and guitar strings. The T-shaped thing is for changing the tune
from high to low tone and vice verse.
The function of the bottle is for amplifying the sound. And I named my instrument as GUINJO because I incorporated the idea of a guitar and a banjo.
