I don't know the digitech circuit, so I can't tell you what to do. But I'm guessing it does feedback in analog, so there is some amplifier circuit that sets this feedback gain. Somehow, the gain in the one unit is off, and it can't reach it's max value. It probably even has a small potentiometer on the board used to calibrate this, and the pot in your unit has gotten off from the proper setting. You might try getting a service manual from digitech, or try adjusting them yourself to see if anything fixes the problem. I know somebody else on the list had tweaked some pots in the 7.6 to get a longer delay time, so maybe that person knows how to fix the feedback too.
