I spent a lot of time trying to solve that problem with the X4. The best compromise I found between a nice sounding harmony (in "full mode", that is with 3 more voices) and little feedback was a ratio around 55/42 (main voice/harmony voices volumes). Maybe this will work reasonably for your buddy...
