LTSPICE - .asc file, model and sub attached.
In this basic tremolo control, I cannot avoid what seems to be the input signal riding the output.
As is, even if the JFet is cut (??) I still get the equivalent of the input signal, at the output.
Sure it is more than 100% modulation; done on purpose to put in evidence that the JFet is cut.
Around this for many hours, I supose I am wrongly biasing the opamp but cannot see where or how.
Comments will be appreciated.
