With no pin numbers showing how can we tell if the op-amp is connected correctly?? That is the one aspect that has not been verified.
i haven’t thought about that and that makes sense.Then the circuit won't work properly, since it depends upon negative feedback from the op amp output to the filter components to generate the filter functions.
The op amp is not a buffer, it acts as an inverting amp.
Why would you think the tone control would work if the op amp wasn't?
