Is this possible? I don’t want to break anything, so I haven’t tried it, but it seems you could soften transients with it. Anyone tried it?
I have not tried it…sounds plausible…and awesome! 
It won’t hurt anything. The results will not be what you think. (Usually)
It just seems to lower the volume a bit. Very slight changes.
Isn’it a kind of low pass filter?
Should be usable as long as nothing greated than 5V is sent it, I guess.
