I tried a MXR Noise Clamp and it cut the noise floor of my Pharoah but when used loud with the fuzz up, it didn't stop the feedback... Is there a pedal that can do this? A pedal that will let me have full fuzz at super high volumes and NO FEEDBACK?? please someone help me! I don't know whether my Noise Clamp was broken or something... if someone has one and it works in my setting effectively please say!!
