I got my memory boy for Christmas 2009 and well it pretty much does what it wants when it wants. At first it seemed to work fine but I noticed that all of the knobs seem to be so sensitive as everyone was complaining about, so then I switched back to using my boss daisy chain one spot power supply, and well it seemed to work perfect until today. Now even with the ehx power supply I am getting a super high pitched whistle only when the delay is set to its max delay time. As soon I turn the delay knob to about 9 0 clock the whistle goes away. I think this is a damn shame because this pedal sounds so damn good when it wants to work. Anyone else having this problem?

I also think EHX needs to step up on this one because it seems to be an ongoing saga with this pedal.
