There are tons of good Cab IRs out there, both free and with a small fee. I've had good luck with Redwirez OwnHammer, Catharthis, and a few more (I'll post a more detailed list when I'm in front of my computer). I use Redwirez MixIR2 to load Impulses and blend them. When choosing IRs, I suggest leaving the tone controls on your amp sim flat, adjust the gain to taste, and then choose 2 IRs. One IR for the low end bass response you're looking for, and then another for the high end to blend together. Once you've found 2 IRs that you dig, play with the mix levels to blend them to your liking, and then tweak the controls on the amp sim.
That should be enough to get you started. I could send you some IRs if you'd like as well. I won't share any of the commercial IRs (buy them from their respective creators, please!) , but I do have tons of free IR files from many sources, including Redwirez and OwnHammer.
What IRs are you guys using? I know there are quite a few Torpedo Live users here on RT, as well as Kemper and Axe-Fx. I'm sure there are tons of IRs in use around here. I think it would be cool to put together a big package of free IRs based on what everyone here uses. We'd have to credit the sources of course, but it would be doable.
Oh, and my name is CaseyCor (or just Casey if you prefer). The Rock God thing is just a little nickname the website gives you based on how many posts you've made here
I'm not nearly pretentious enough to call myself a Rock God, haha. A bit of a dick perhaps, but certainly not that full of myself.
Let me know how your digital guitar amp exploits go! I'm new to a lot of this stuff too, just making it up as I go along. I've been playing with different plug-ins on some tracks I recorded for a couple hours every night, and I keep finding more and more interesting stuff. Boosting some frequencies with a graphic EQ after the parametric to compensate for the low/high pass filters, using channel strip/pre-amp emulation plug ins at the front of the signal chain, running a DeEsser before the amp sim, using bus sends to create a Wet/Dry/Wet rig (which sounds huge!). It's been frustrating at times, but overall a lot of fun.
