Maybe not brighter, but “clearer” than most. You might like the CN captures in the packs if you want them a little darker in the top end.
My advice to any new Fractal user is pretty simple. Treat it like a real rig and it will sound like a real rig. Start with your cab, since that’s the biggest factor in your overall tone. I’d start with Mix 01 as a general rule of thumb since the 57-121 mic combo is such a staple.
Then choose your amp (no effects yet) and tweak it like you would with a real amp using just the Authentic tab in the Amp block. Also, try to use the closest Impedance Curve to the cab you’re using in the Speaker tab in the Amp block.
Once you’ve got your core amp tone, add one effect at a time in the same order you’d have them on your pedalboard. If you run all of your pedals into the front of your real amp, then run all of your effects blocks in front of the Amp block.
Keeping it simple will give you the most authentic results. The Axe-Fx let’s you do anything you could possibly want, but just because you CAN doesn’t always mean that you SHOULD.
I’ve been using Fractal products for 8 years. The modeling is so good now that I rarely feel the need to adjust any advanced parameters and I’m easily able to match my real amps using just the Authentic controls in the amp block.
I hope this is helpful. Just remember to have fun.
