In my experience the Green Russian is a lot different from the Black. I tried out the nano green muff and while it does sound good it couldn't replicate a few of the sweet spots that I like on my Black Russian.I'm no Muff expert, but wouldn't that be the Green Russian BM that came out a year or two ago? That plus a Bloop wouldn't take up a whole lot of real estate.
That being said the JHS Modded Green Muff is on my fuzz GAS list for other reasons. I'm confident it would seat my Mastotron for sure.
