phantom powered fet preamp question


 

Hello,
?
I build this preamp and I was wondering if there is a way to control the audio volume?
My best guess so far would be to add two capacitors beside C3 and C6 and wire a dual pot. But it seems very ugly.
Thanks a lot and have a nice day.

This is basically unity gain and going into a mic preamp. That’s the best place to adjust the gain

Thank you
I forgot to mention that I want to put it inside an instrument. That's why I would like to have control of the volume.

If you have a look at Siegfried Linkwitz's site, there is an alternative method of using that microphone here?
