How about a volcano as an LFO!

Did anyone see Sound Waves on BBC4 last night?

These is a section where the presenter climbs up Mt Stromboli to hear the ultra-sounds of the errupting volcano.
They do it by listening to a 70Hz frequency being modulated by the 2 Hz frequency of the sound waves created by the gigantic chambers inside the volcano!

Now that’s an LFO!

(I just had to post this in Other Gear)

Hahahah, I didn’t see it…

But I like it.

Well shit, now I need to buy a volcano. I got the GAS, friends
