I'll take a look at those. Thank you.

Hope you find what you need!

Stumbled upon them many moons ago, quite some nice stuff there.

Lots of great resources here. Thanks to all!

I've used TONE3000 with success in the past for when I was looking around for guitar cabinet IRs

Honestly I wouldn’t go for one huge pack, but if I had to pick a solid starting point I’d check out the Samplicity Bricasti M7 impulses.
They’re very well captured and cover a lot of usable spaces without being overwhelming.
Other than that, I’d still recommend building a small curated set over time instead of relying on a massive library

OpenAIR is still the gold standard for academic-quality captures in 2026 — great to see it mentioned earlier in the thread. For anyone who hasn't also checked them out, EchoThief (echothief.com) has over 100 real-world environments that lean more creative (bridges, caves, stairwells), and Voxengo (voxengo.com/impulses) has a smaller but very well-chosen set of classic spaces. All three are still actively maintained and free.

Both are paid services, but when it comes to guitar cabinet IRs, I think Engineering-Alliance
https://engineering-alliance.net/produc ... -response/ (https://engineering-alliance.net/product-category/impulse-response/)
is the best, and for bass cabinet IRs, TacoSounds
https://tacosounds.com/collections/bass-irs (https://tacosounds.com/collections/bass-irs)
is unbeatable!
TacoSounds also sells a variety of guitar cabinet IRs, but since I’m a bassist and don’t know much about them, I haven’t tried them yet. I’d recommend TacoSounds’ guitar cabinets to knowledgeable guitarists, but Engineering-Alliance really does offer outstanding value for the money.

Can anyone recommend some acoustic guitar IRs from personal experience that help make a less-than-great DI acoustic sound more natural and microphone-like?

Out of the IRs and links collected in this thread, which ones would you consider the best starting points for this purpose?

I’m not looking for a heavily processed sound—just something that reduces the typical piezo/DI character and gets closer to a realistic studio mic’d acoustic guitar.

My KVRDC entry this year is a whole set of outdoor impulse responses of a single canyon. It's sort of an oddball idea that took way more work than it rightly should have, but the results are neat.

Check out the Canyon Soundings product page for download, or the post in the KVRDC26 forum for some additional information/discussion.
