What is the basic differences on the new hi gain channel other than more growl
Are they very similar in the way that if you favoured the GNL you would dig the new Channel
And vice versa with the FSM/Hydra
Consider the Gryphon versus GNL. The Gryphon came first, and was meant to be a "vintage high gain" sort of channel: lots of gain ("modern" levels) but vintage-voiced. Gavin (Firejack) made clips of it which sounded a bit different from what I had intended, partially because he used a mild boost in front of it. The attack was more solid and it had more growl. This sort of response could be obtained from the Gryphon if you used just the right pickups/guitar/playing technique, but in general I couldn't recommend the Gryphon to get that specific sound. So the GNL was born. It had a bit more solid attack while keeping the rest of the Gryphon sound "intact". It wasn't a huge difference but for those who wanted sounds like Gavin's, I would have recommended the GNL.
There are some people who wanted to hear even more aggression from the Gryphon or GNL. They wanted that particular sound "but more aggressive". The thing is, you can only modify an amp so much in one particular way before the balance is thrown off in some other way. The GNL, if modified any futher in those aspects, would lose some growl and start becoming basically too much like the FSM. Some people think the FSM is "growly enough" but some don't, so it's not a good answer to just tell people to get the FSM instead.
The design with which I'm replacing the Gryphon/GNL has no trouble in that regard.

With the different circuit architecture, I can keep the growl and add a bit more aggression yet. The attack has a bit more chunk than the GNL and it sounds a bit meaner overall. No one seems concerned with the most subtle aspects of the Gryphon's sound being lost, so this is an obvious choice for me. Even so the design responds nicely to rolling the gain control down (and turning edge/crunch switches off).
As for FSM and Hydra, that's different in a way. The Hydra was not originally intended for very aggressive attack and bite; its intent was warmer/smoother/thicker sound than the Chimera (specifically, the first Hydra was made for a Chimera owner who quit his heavy "death metal"-ish sounding band and wanted to get a more 80s hair metal type sound). I eventually modified the Hydra so that it *could* sound a bit more aggressive/bitey, but I'd always recommend the other designs first for that (including Gryphon) since the Hydra wasn't very strong at this. However, there were a couple Youtube clips of the Hydra which people keep telling me "I want that sound!" and "make me a Hydra!" because they hear a really tight attack in the clips...but I know it's very unlikely that they'll get that sound from the Hydra. Part of what they're hearing is the unusual speaker choice (I forget which, but they're not the usual Celestions), the fact there's a powered subwoofer being run at the same time, camcorder/portable recorder/cell phone mic clipping (and the sound of the room), and of course the specific choice of guitar and pickup. For the sounds in those clips, I would have generally recommended the FSM to people (and later I made a "lead variant" as I described above, which helped get even closer). Even so I knew I could do better to get the kind of response people were actually expecting...but it wasn't really there in any of my designs at the time. I wanted to add some aspect to the distortion and raw voicing which sounded similar to what was happening overall in those clips.
Plus, I didn't want to have several high gain designs which were a "spectrum of similar sounding" designs, with some being different to a relatively small degree from the other (Gryphon versus GNL, or FSM versus CSM). If I could make a range of sound/response in a design that most people want for Gryphon-type sounds "optimized", I could make that the "vintage high gain" design. And if I could make a range of sound/response in a design that most people want for FSM/CSM/(and Hydra) type sounds "optimized", I could make that the "modern high gain" design. That would end the concerns over whether one design was better for X or Y. The choice would be much easier, and it would be more likely that I could meet people's expectations with the amps.
That's what I'm doing now.
I hope that answers your question.

I can't really say much more. Describing sound isn't easy since it's subjective.
I could say "they're the best amps ever, in the world, in all history" though.
Seriously they are and you should buy them all.
