I found it hard to love an IR until Ownhammer did the Scumbacks. They come to life for me. The 412 SLM M75 is killer. Haven't tried the H's but from the demos around the time I bought them, the M's are the best. I'm holding off a bit on playing again because my new job is killing my hands as it is, but I hope you find your IR. Free ones are not good, the methods they use to make them and the gear is very basic stuff that shapes the sound, but there's no life or feel to them like the Ownhammer impulses. You might still need to EQ them, but you wont be notching out frequencies that take the life out of them.

I don't know how the current packs look, but there weren't a whole lot of impulses to go through and I actually liked that because I remember going through a landfill of impulses back in the day too.

This one, I decided was my goto out of them all. I want to say I may have modified this one, but I think I ended up just renaming it: https://db.tt/td2e6t6Z

There's no way to redownload my pack, and they are improved now, otherwise I would not share this particular impulse file. It's named MD1 because I was trying to get Mark Day's Flying High Again sound with it at the time.
