I’ve had some pretty similar problems to the ones described in this thread. I bought my 2880 used and it included the stock CF card, which worked perfectly for a couple months until it just died overnight—couldn’t play or record, or even enter “record ready” mode where the record light is blinking insanely fast. I ordered a Transcend brand 133x 2GB CF card and it made the 2880 functional again, but after a few hours it started glitching. Loops would include patches of silence upon playback that came out of nowhere but wouldn’t go away unless I erased the loop and started from scratch, sometimes very loud popping sounds would happen during loop playback, and sometimes fresh loops would include a random 1/2 second snippet of a previously recorded (and supposedly erased) loop. I read online somewhere that the 2880 can be picky about which cards it gets along with, so I ordered a different card—a SanDisk 2GB 100x. It worked like a charm, and I haven’t encountered any glitches since then…

Slightly disappointing that weird anomalies like this would exist in such a great (not to mention expensive!) piece of gear, but hey, those kinds of anomalies are part of the character of EHX effects… right?
