That sounds like a real Dumble. The Randall modules are just not going to give you a sound that is gonna get in the same room with a Dumble. The closest & best I've been able to do to get that sound is the following combination.
Egnater EG3
Fulltone Fat Boost
Marshall 2X12 - Celestion G1265 or Greenbacks (both?)
This didn't even totally get me all the way there, but it was how I found my own Egnater sound that I like the best and actually prefer at this point.
Also I might add that the original Egnater IE4 preamp, channel 3 was even better! (In my opinion)
