I have been working with a distortion circuit that has an op amp amplifying the volume before sending it through the diodes. The op amp is configured as a non-inverting op amp with a feedback resistor and capacitor as seen below.

I would like to know, how can i eliminate the echoing feedback from this circuit. As in when I play a sample of music through it, at full volume, the circuit begins to get this fixed echo effect. Feel free to ask for more of the circuit if needed.
