Just one more variation on the Distortion+

[majormono]

For those who are still concerned about more variations on the good 'ole Distortion + topology...
Yes, yes... this was "what do I want to build today", but since I'm just not simple enough I had to
design my own take on this classic.
Nothing too fancy, take a look at the schematic if you are interested (www.grol.de/diy/AnyplusSch.gif).

Now for the crazy stuff everyone seems to like: Opamp comparison.
I've tested all single opamps I had laying around and did a little comparison take to get a better picture of
the real differences. Included are the top-runners TL071, OPA637 and LF351.
You may go and take a hear but don't expect good playing (www.grol.de/diy.htm).
There are also layout and PCB files if you dare ;-).
