Need input buffer for Baxandal tone control

I need input buffer for baxandal tone controller. Schematic is given below
Thanks in advance

Hi. Looking at resistors values , i doubt that you need a buffer at all for 10k input resistance. Most sources are capable of driving loads of 1-2k or even less. If you want , can use any audio opamp, capable to operation with gain of 1 , like 5532 , lm4562 , also there are may opa series . What is your signal source ?

If you use the inverting buffer circuit, the feedback resistor can be lowered from 10k,
and the gain will decrease from unity in proportion, even all the way to zero.

For example, if the feedback resistor is 5k, and the resistor to ground is 10k,
the gain is -5k/10k or -0.5 (-6dB).

Of course, you could instead use a 10k volume control before the buffer.
