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 videos i took on it do not sound like it does in real life - you can't really tell much difference between this and a drum kit in them.
It has four strings, and although being a bass it looks nothing like a real one - so maybe i should call it a harp.
Step 1: The Small Pieces
2) tuning edge
3) base edge
Oh, and get a box the size of a PS3 box.
