Derek Holzer, I don't know anything about curcuit boards, but isn't
the distorted sine problem a design flaw, not a feature flaw? What I
mean is, even if that waveshaping knob wasn't included, you probably
wouldn't be able to get a less buzzy sine. It just takes a good set of
ears to make sure you got the waveshape knob set right. Other
oscillators are designed differently and have imperfect sines that are
not buzzy, but have some additional harmonics, which is much better
than buzzy IMO. I think this is the case with Plan B VCO and Tip Top
Audio VCO.
