I'll be the first to admit I'm sort of rack retarded.

I've got a 5150 if you couldn't tell, and I've been using an ISP ProRack G for some time without any problems. I recently picked up a DBX215 2 channel 15 band EQ. I set it up like so:

Pedals -> ISP tracking in - tracking out -> 5150 input - 5150 send -> EQ in - EQ out -> ISP in - ISP out -> 5150 in.

After maybe 30 seconds or so it sort of farts out. Still works but I know when something isn't right. I know it wasn't the decimator cutting the sound out, but that's about all I know.

Advice? Tips? Send my gear to you?
