THAT preamp with 3 Band fixed EQ

[JohnRoberts]

The components are OK, but using one opamp for mediocre results when using two would yield much better results is cheap. You may have noticed I'm not a blind proponent of minimalism. As a bonus, putting these two stages in series will result in no phase inversion, which may or may not be an issue.

+1 getting the polarity right is important if you use bypass switches. You don't want polarity to add another variable.
