Default Baxandall tone control.

I have just built this tone control , it works very well ,but I need to attenuate it a bit , as the v/c on my amp is only just off the stop , no distortion , what would be the best way to attenuate it , Mick.

Try changing the 220K on the first stage to 100K - that will drop just over 6dB of gain.
