If you have to pay to get decent captures.. it sounds like a money pit.
not only that, it sounds like the explosion of IRs a few years back when thousands of IRs flooded the free / pay market; now it's an overwhelming number of captures... and IRs
Even if I think about my Fractal FM9 MkII Turbo...I can take one amp, and let's say 10 cabs to pair with that one amp; now I have all kinds of tweaking, mics, mic placement, etc. it's probably well into 100+ options. How do you remember which combination of settings is which, and then compare them?
Blue Cat Audio's Axiom contains their Destructor plugin, which comes with presets that represent real or imagined amps, but under the covers it's a tone shaping / sculpting tool. Once I started using it, nothing even comes close.
Turns out my favorite plugin, PolyChromeDSP McRocklin Suite, is conceptually a simplified version of Destructor tone shaping approach in a UI that's more familiar to guitarists.
As I thought about it, Destructor is very similar to my old ADA MP-2 with pre-post EQ, and a selectable pre-amp model...which is also similar to my ISP Theta Michael Sweet gear.
Tone shaping and sculpting is all about EQ. It works great for me, and I don't have to sort and sift through hundreds or thousands of IRs, profiles, captures, etc., then compare and contrast them.
Here's what Destructor in advanced mode looks like, with three sections: pre-, destruction, and post-.
