Thanks for saying all of that. It means a lot to hear these things are making a difference and that you’re having so much fun exploring them!
That pack came out before I started making stereo room captures, so if you’re just using a single 57 and want some room ambience, you can try a couple things.
1. Load the HWAT Room captures into your FullRes slots. Pick the one you like the best and put it in cab slots 3 and 4 panned hard R/L. Go to the Align tab and nudge one of them back until you get some stereo spread (I’d start at around 20ms and tweak more/less time depending on what you want.
2. Use your HWAT 57 and try the blending in the FullRes YA Brit 4x12 M25 (however they have it labeled) stereo Room captures from the Legacy cab bank. It may sound great “as is,” or you can use a high cut on the Room captures if you need to darken them to glue them into your tone a bit easier.
Just like the sound engineers on all of those great records, enjoy experimenting with stuff. You’ll discover some cool ways to get interesting sounds.
