Hello. I have noticed the R3 was increased to 220K. (Used to be 100K, wasnt it?). The thing is I want to reduce volume just a little more when pot is on zero. (I believe I have R3=100K in my amp). Shall I put another 100K across it?? Thanks!

No, leave it. The resistor just sets the lowest threshold. No worries.

What resistor should I reduce then so I can achieve a lower volume when VRM pot is on zero?
Thanks!

That would be the one, but it seems very extreme to go lower than 100K. Well, If you do put another 100K in parallel, you will drop the lower voltage even further and also the volume.

I finally tried a value around 60K, and It sound right for me!! I like it.
It this value extremely low? Voltage drop is too high?
