Iv'e had a MXR Carbon Copy for about 3 years and I love the Oscillation it does, and how easy it happens. But now it has stopped doing this, the delays just fades out. If I want those Oscillation tones I have to set the "Delay"knob between 10- and 7-O clock and the "Regen" knob at 5 O clock. Anyone else had this problem? - Lars Ove, Norway.
