Knex bass guitar (Harp)
This is a tunable bass guitar - that I am going to add to Knex band.You can actually get a tune out of it and it sounds much like a bass (However i am not a bass player so i wouldn't know well).
I managed to get 'Smoke on the water' out of it and it sounded pretty realistic, however all the video...
