Yup. Good call. I was thinking the same thing about R2. Ground should be ground and not a spot for unwanted potential.
More importantly, any error current through R2 will set up an error voltage that will be in series with the signal, thus, amplified. That's not what you want.

Hi, Tom, I don't understand, do I just have to remove the R2, or do I have to bypass it to reconnect the SG to GND?
