Ok since impulses are getting quite popular around here, and lots of people are asking questions here and there. I figured I might as well make a thread about them. What are impulses? They simulate everything past the pre-amp stage. I don't know the technical stuff but who cares? All you need to know is that they are cab sims and a lot of people seem to think that they sound way more realistic than for example: the pod cab sims. How to use impulses? 1)First you need to download impulses. Just google them up and you should find plenty of them. Here's a nice collection by Teddyboy from the AndySneap forum. Lots of good stuff. http://rapidshare.com/files/151587481/Teddyboy_s_Impulse_Collection.rar 2)Download a program to use the impulses. Two popular ones are(they're free): Voxengo - Boogex and SIR: SIR1 Edit: Another popular one, http://habib.webhost.pl/vst_eq31.php (thanks Plankis) 3)Open up your DAW and load the plugin, voxengo or SIR1 doesn't matter but I like SIR1 more haha. It should look like this and for voxengo keFIR 4)Ok now it's time to load up the impulses I've circled the buttom you need to click. Click it and find your impulses. They should be wav. files. When you're done you should have this: or 5a)Open your gearbox, pod, revalver, amplitude, etc. Turn off the cab sim in your modeller. You should end with a shitty, fuzzy and totally epic phailz tone. It's supposed to be like that, don't worry. Record your riff now. Make sure you record on the track where you have the impulses running. After you've recorded, play the damn track. OMGWTF, it sounds like a real mic'd cab. Congratulations you are using impulses! 5b) Now if you want to run a real amp head through your impulses, you can. Make sure your cab is connected so your amp has a load and won't explode in your face. Use the fx-send or pre-amp out. Now just follow the 2nd half of 5a and you should end up with an awesome tone. Ok that's it peeps, if there's anything I missed, just ask away and I'll try to answer them. Note: you will not magically get good tone. It sounds like a real mic'd amp but you still have to tweak. UPDATE 101209 I think most of you guys should have heard of these ampsims by now, no harm in posting them here I guess. Thanks for the sticky, mods! http://lepouplugins.blogspot.com/ http://sites.google.com/site/nickcrowlab/ Lots of good stuff, only thing is you need a DI box(I'm pretty sure you can use a pod for it although I've been getting crap results haha), because you're recording guitar DIs.
