Thanks for the suggestion Travis, I tried that but.... no change, no err messages nothin on the display at all. I'm sure that some of the others can understand my frustration, I've spent the last 1 1/2 years re-inventing myself performance wise with the looping at the center of that and now it has failed and I've got some gigs coming up in the fall. I've been experimenting with Mobius and that may work as a replacement, tho I do have to be careful how much I ask of it running on my old laptop (compaq m300, 600mhz, 382 ram, 60 gb hard drive). I've been quite discouraged at the lack of help availible for echoplex problems. Gibson Canada says call Gibson US, I contacted them and they recomended checking Loopers Delight for help, the archieves recomend Shane Radke, but no one at Gibson seems to know who he is..... and on it goes. I told Jeff (at Mobius) that if my laptop breaks down at least I can find repair people quickly, even if I had to borrow or rent one for a few weeks. So there's pros and cons to using dedicated hardware or software, everything is a compromise. still hoping to find some schematics, who knows if the software approach works well enough you might see my edp on ebay once I get it fixed.
