Hi Alan,

While the opamp output impedance argument is valid, having an extra 5K in parallel would change the resistance curve. I'm not sure how much impact would that have on the user perception itself but could be tried, I guess.

I don't think so, since that would put an extra 5K ohm parallel to your new pot, no?

My guess was reckoning that the output impedance of the op-amp would be low enough to feed 2K5 without any voltage drop.

    would lifting the wiper contact on the volume pot not be enough?
