yes
printing your bricasti through a scarlett 2i2 is a normal thing

can the average person notice plugins? Not attempting to discount the efforts of producers and stuff but like, could you play a song for someone where, all of the tones come from plugins and have some people ask things like, "what amps did you use?" You know what I'm saying?

Record an impulse response of your hardware reverb (with a long sine sweep for high quality) and apply it in software. Then sell the hardware reverb because you just made it useless.

Just add reverb in post.

The average person can notice if something sounds good or not, and adding reverb in post (for example, using the stock reverb plugin in pro tools) can wash out the mix just cause the plugin isn’t very advanced. A lot of post production plugins sound like garbage unless you have good handpicked ones that you know are high quality. I just prefer to use my sampler reverb for example, it just sounds better to me and doesn’t sound as “cheap” I guess

gotcha. '
what do you think of the following: let's say there's a plugin that you like but it's pretty blatantly stock/out-of-the-box from your DAW. Would you ever think of tweaking it by recording, say, a guitar track with the plugin included, then exporting its wav file, and then dropping it back into your DAW and then adding something further from there? Meaning like, another plugin on top of it or just adjusting it somehow, a little to give it some uniqueness?

Don’t put reverb on an already reverbed gtr, it’s just gonna sounds super washed out and distant. You could record an entirely wet reverb track using your guitar track and then put some crazy panned tape echo or delay on it that reverb track or something and then have the reverb+echo track and the clean guitar track mixed at the right volumes together. That way you get clarity of the part and also the crazy atmosphere, just dont mix the atmosphere part too high or else it’ll muddy up your track

I would just use a stock reverb, you'll get considerably better results than going through the scarlett's less than stellar pre-amps not only once, but twice.

Really learn to work with the stuff you have on your computer already would be my biggest piece of advice. If what you have stock on your DAW is shit there's a ton of great stuff you can try out or even get for free, just put in the half hour of work and you should get some amazing results.
