i, too, have a soft spot in hy heart (head?) for the contours of the 
SOU. I have a dodecamodule on permanent loan to a local 
college electronic music lab and i'm familiar with the SOU's 
loopy, 'graceful' sort of character. 
> i believe the SOU was a source of inspiration for the Wbug but 
the similarity is very abstract when you get down to resistors and 
capacitors. Under the hood, the Wbug design is very unique (and 
unusually original by today's standards) and IMHO the 
comparisons with an SOU are blown a bit out of proportion.

The Vactrol controlled LFO, sample and hold and linked Vactrol 
smoothing filter are taken verbatem from the smooth source on 
the 266. Any difference in "feel" would boil down to the less 
random nature of the recursive design. However, you control the 
level of randomness with the knob settings, so you have a LOT 
more control of the output character than the original SOU.
