There currently isn’t an Eventide-based resource for preset sharing where you’ll find immediate results. The best recommendation I can make is to research the gear of the artist’s sound you’re trying to emulate. Find out what gear they used during that recording period using websites like equipboard.com and guitargearfinder.com. You can also use popular gear forums to ask if anybody knows a particular signal chain for the song you’re trying to match. Armed with that knowledge you can find algorithms on the H9 that will emulate that sound. There are some H9 User Facebooks groups you can join as well, where you can ask to see if anyone has already made a specific preset. I’ve found that Google searching a particular song can uncover articles where engineers, producers, and artists themselves talk about specific amp and effects settings. This also uncovers gear groups where such topics are discussed.
