I was waiting for a topic like this. I got my Snakebite Platinum last week and have been playing it quite a bit. I've only run it in the RM20 through two Bogner Cubes with V30s, but the sound is what I'd expect a recto to be. It's thick, somewhat loose, with a metallic/synthetic grind to it. It's in your face and rude which is perfect for rhythm, but also has great sustain for fluid leads. I was hoping for James Murphy's tone on Testament's Live At The Fillmore and think this mod delivers.
I will say that it has more options than I need. Truthfully, I'd ideally get the Snakebite with the channel select and venom switch. All the other options really change the mids and top-end, which is great but much more than I'd ever need. Maybe in the RM100 with a 4x12, which I haven't tried yet, you'd need the choices but to me, I don't need a "do everything" mod.
But overall, the tone this mod delivers is golden. I have heavy mods from the SG Afterlife to JF Damageplan, and this one bridges the gap. It won't be replacing my Afterlife, but it definitely brings something different that I can use.
