Hoping someone can help with this one.
I'm looking to transition some of my sounds to be based on the Justin Derrico GoT presets (based on the Shiva). I have FM 8.01 loaded but i haven't yet re-saved this preset.
It sounds great as it is but if I save it with the new firmware it loses something. It's almost smoother and likely more accurate but not what i'm after.
Can anyone indicate what amp changes I can revert back to in order to retain this original sound and feel?
Some of my other main presets have a similar change in tone which I'd like to revert back to as well.
I know I could stay on an old firmware and if that's the actual answer then so be it, but I like the other new improvements so I thought i'd reach out and ask the question.
Thanks for any help
Just to save people some time, I think the clear message, that I really should know by now is "don't chase a Unicorn".
TLDR: After various tests the outcome is I tweaked some settings and found something I like just as much and its really close.
Long version:
1. To make sure i wasn't imagining anything I created a guitar loop as the input to the FM9
2. I recorded the 'good, non re-saved' JD patch into my DAW
3. I recorded the 'bad, saved' JD patch into my DAW
4. I aligned them and phase reversed one of them.
5. Result is essentially 'what's missing or added' which was some complex high end artifacts amongst other things.
6. I looked back through the previous firmware and highlighted items to try and change.
7. All the key ones were in the Cygnus X3 update including Preamp Bias, Triode plate Frequency and Negative feedback.
8. I played with those a little bit, to see which helped (and the master bias control which was mentioned previously to me) and I found a combination that I think is great.
9. One observation was that i also reduced the master volume and the preamp gain by a very small amount which cleared things up.
So that's my result, pretty happy and it does now interact and make the guitar sing like the original patch and so I will put the effort in to do the same with my other patches that have changed.

Thanks for all responses.
