Instead of reducing input gain you can increase the Compressor Threshold.I'm liking it generally about 2 or a bit less, but I also find that I'm having to back off on the input gain to the amp quite a bit when I use it. I tend to use mid-gain amps, or amps on the verge of breakup. Dialing in the Gain Enhancer really seems to add gain more than I'd expect pure acoustic feedback to do.
