   This is one of those low-cost tricks that are detailed in ElectroNotes.  
   Seems you can get 6 decent quality op-amps for cheap this way, but it's 
   not very versatile.  

Except for the "decent quality" part -- they're pretty noisy.

And they're not really opamps since they just have one (inverting)

They have been used for several tubey sounding fuzz circuits since
their overload characteristics are kind'a gentle.  (The Anderton
"tube" fuzz, the ElectroHarmonix some-name-with-the-word-tube-in-it
fuzz, etc.)
