I frequently use my Torpedo Live and nearfield monitors to play my amps at reasonable volume. I played around with the factory IRs and downloaded some of the user IRs on the site, but none of them sounded very good. I was skeptical that I could get the thing to sound good, but heard enough about Ownhammer to give them a try. I play through vertical recto 2x12s when I use cabinets. The OH site has a free download pack with some limited mesa 4x12 IRs. Holy cow! They sound fantastic! I didn't even get into the detailed part. I just demo'd the quick start models and found a couple that sound right on the money when I A/B them with the real cab. I'm really happy with them. Now I can play the Archon 24/7!
