[sdiy] Low Pass Gate is soooOOOOooo sweet

[Oren B. Leavitt]

Thanks Harry,

I was wondering about that, too..
BTW what's the spec on the 5C4 / 5C4/2 ?
I built a 4 stage phaser some years back around 5C4s that is deliciously smooth
and 'wet' sounding.
As you speed up the modulation rate the sweep range becomes shallower and
asymmetric in shape which adds to the charm.
I'm interested in trying the 5C4s in the LP Gate circuit, as I have lots of them.

Thanks again
Oren
