It's not correct to think that PS bypass caps at the chips will solve all 
decoupling problems.  If you have effects due to ground loops, etc., they 
will not help a bit.  Even if you don't think you hear any problems, the 
oscillators will almost certainly sycn over some frequency range.

Yes. Use it to make a Tri -> Sin shaper.  That's what I'm doing on The Teezer.
