My random idea........
How to turn a bass drum into a shaker.
You know those "bead curtains" that people hang up on their door frames?
Get one with wooden beads, cut the length so it fits inside a bass drum and secure it to the top of the inside of the bass drum shell.
Everytime you slam the pedal onto the head, you'll get a nice shaker effect from the vibrations.
Yes? No?
Or replace the beads with bottle tops and make sure each one touches the other one.
The potential is limitless.......
Like it, or you could put those jingles into the shell like they do on those goofy snare drums. And they say drummers aint be all that good in the smarts department, fooey
