I contacted Nik with these questions. Here’s his responses. He responded almost immediately.
“Thanks for the email.
As for the Leviathan, it's a slightly modified Friedman Butterslax, if you're familiar?
It's a 3 channel amp, with clean, and 2 types of OD channels.
As for the Gargoyle, it's similar to the Fortin Meshuggah amps, which stems from design similar to our Chupa/Yeti, so they're Jose Arredondo type of 80s high gain amps.
The Gargoyle is voiced differently, with a bit more gain, tighter, and a bit darker, compared to the Chupa/Yeti.
It's a single channel amp.”
And this...
“As for the Molecular, it's voiced differently.

It's a bit smoother, darker, not as snarly as the Yeti, more towards lower mids.
