problem with MXR Flanger pedal

[axeman81]

Hey guys,

I just got a brand new MXR 117-R Flanger pedal, and I am very happy with it so far.
Of course, after a couple of days use, it started making a weird pulsating noise in the background. It varies in speed when I turn the "speed" knob. It sounds like a single low-pitched click...like half a heart-beat if you like.
It's like having a metronome in the background of the flange...not good.
I tried swapping guitars and batteries but can't seem to get rid of it.

Any ideas, before I send it back?


thanks,

- Rune.
