could have bought a CD of somebody else playing the same tune a darn sight
better than I can. Nonetheless, I have since gone on to more advanced pieces
and hope, one day, to produce original music of my own.
Should I have bought the CD instead?<<

That sort of makes sense if those on this list are diy'ing old outdated
stuff to learn and become design engineers.  But in most cases it seems like
many already know their stuff pretty well or if they don't, they're just
copying circuits to prevent from simply buying a piece of gear only to end
up with something probably inferior and without a nice pretty professional
look to it.

As for the guy who was originally asking about EQ circuits, it seems like he
might have missed the Symetrix and Orban schematic links to also look at.

And just to add to my previous post, ebay is lousy with parametric EQ's.  I
found several different Orbans all with starting bids between $15 to $50.
Found Audioarts mono and stereo units with starting bids of $40 to $70 (one
at $435 though).  $150 for Audioarts stereo unit from some studio.  Ran
across Roland's old and expensive digital parametric, the first time I've
seen one in about 15 years.  Great deals are all over the place.
