MHG dark? The EG3/4 is much darker. Here's the ranking dark to bright:
EG3/4
MHG
EG5
The MHG is more like an SL2 that has more gain and is a little tighter. You can make it sizzle with highs and cut with mids. Try it. But don't use too much gain or you'll lose definition and get buried. It has plenty of sustain around 1:00.
I've had all of the modules except the ERECT, and I've compared them side by side in my MOD 100. EG3/4 is dark, just like my Mesa Mark IV's lead channel, with less gain. Smokey - I think that's how they describe it. A good sound if you like your leads with a little less bite.
