Anybody got a bass drum circuit?

[Tom Wiley]

I have about wore out my proto board trying stuff but I can't get a
satisfactory low frequency "boom" like a drum. It doesn't have to be
music quality - just a window rattling boom. I found a zillion circuits on
churps, tweets, wa-wa and everything else but not much for low frequency
audio stuff beyond sine and square waves. Possibly it can't be done
without a whole pot load of components.

Anybody got a schematic?

Thanks

Here's one I made about 15 years ago, and drew previously for a
similar query:

Of course, for just a drum, you don't need the 12-way rotary switch;
just choose the fixed components for Bongos, or whatever.

Thanks. I will give it a try.
