Hello, I’m new to the forum. I just got a Hot Tubes and love it. I’m trying to understand it a little more which is what got me to post this instead of just lurking. I did a search and didn’t find the answer to my questions.

The Hot Tubes is labeled as a distortion but it also talks about a “paracyclic filter”. Is the Hot Tubes a tube filter that is very overdriven? A tube preamp very overdriven passing through a tube or solid state filter? All tube or a combination of tube and solid state? I know the tubes are getting a proper amount of voltage so they are obviously doing something (or everything), I’m just curious of what is going on.

It sounds surprisingly big muff like too. Is there some sort of Big Muff based circuit. But, it can sound pretty non-distorted too, but always sounds filtered.

Anyone know about the function / type of circuit in there? Not that it matters, It sounds great and I like it, I’m just curious.
