Man, a lot of you are really overthinking this update.
If you‘ve got a preset that’s sounding really off with Cygnus, go to a new, empty preset and start with just the amp and cab block. You can start with the same IR but really, over the last few months the one thing that I’ve confirmed time and time again is that if the preset is sounding too different from Ares to Cygnus, the IR is the first place to start and the quickest way to get back to where you were, usually with better results.
I rely on the IR to get 85%-95% of the tone and the amp block to fine tune it. For the Floyd Rose guys, the IR is the tuning machines and the Amp block is the fine tuners. If you settle on an IR that‘s kind of close, you’re going to spend forever trying to figure out where the hell to dial out the sound you’re not digging. (Unless we’re talking about the Mesa amps, in which case, you really need to tweak the amp block).
Maybe the absurd amount of IR’s I’ve collected has lent itself to that realization/ability to sift through so many to find one that works so well, but it’s definitely given me the best results. The kind of results that make you more excited to try new amps out instead of spending forever tweaking one preset to sound good.
At the end of the day, turning the knobs and seeing what they do won’t break anything. You won’t even lose your presets as long as you don’t click Save as you’re tweaking.
