[sdiy] favorite "magical" opamp?

I try to use the CMOS 4069 hex inverter as an op-amp mode as often as
possible, not for being neutral or linear, but for great saturation and
character.

I use a lot of TL07XXX's

I dont really even question it in most cases unless I KNOW i need something
better, or unless a circuit doesn't work the way it should and I go off in
search of something that works.

(but even that switch is often just from a TLO7x to a TLO8x or a TLO6x.


Occasionally when reading an article or forum post, or when reading the
daily SDIY posts I come upon people touting one opamp as WARMER or MEATIER
in some situations.




SO....Looking though my collection of chips I am noticing that I don't have
a lot in the way of OLDER opamps. I have TONS AND TONS of 741' and 356's. A
few 1458's and 4558's.
It sure would be fun to have more opamps to switch in and out of a circuit
to be able to change the characteristics.


SO...in the interest of having some fun doing A/B Tests and also in the
interest of inspiring some late night circuit design, I would really love to
hear what opamps you
think are vital to have in your collection and why.

Remember, the more character the better.

And character is a very subjective, so maybe explain why you like that amp,
or if there a few you like in different situations, maybe explain why.



THANKS!
