Maracas / Clave

Nothing special here. I just like the sound of this vermona ER-9. And if you take a look at the schemes you see that is needs shockingly few parts. Especially the maracas sound kind of whoshing to me - i breadboarded them and found some nice possibility to alter the decay.

Not so easy was to make the white noise-source with a unipolar powersupply. I had to adjust a very exact bias to center the noise of a bc547.
