m = milli = 10^-3
ml = milli litre
your 10 to 40mVdc is what should appear
or
10mVdc to 40mVdc
I prefer not to leave a number dangling out on it's own. It can be confusing.

I think 3K9 on feedback is to low for TL072. TL072 have low current output capability. You must trade-off the distortion and S/N ratio.
Usually I will choose NE5532 over TL072 because of current output capability.
Most recorded music which has gone through an analog mixing console was probably processed by lots of 5532s anyway...
That layout is not good at all, it won't give anywhere near optimal performance. Specifically the distance between the chip and the supporting components and the large loop areas, see my post #39.
