Hey UnF, it's a little hard to judge when I can't play with your settings, but maybe if you can manage to give the guitars a little more punch/power, the snare like it is now sounds quite good. So maybe if you make the guitars/vocals a little louder, you can push the master buss a little more without hurting the drumsound too much. I'm not at all for going 'as loud as possible', but I try it nevertheless because when you get loud easily, it sais alot about the quality of the mix I think. I learn alot from making the mixes louder to be honest.
I know it's hard to find free Nebula impulses. Advantage is that they're not really expensive mostly. The NAG Tape is a real keeper, but not only because of it's low price, that's for sure. The R2R from CD Sound Master is more expensive, and there's loads more of tapesims packed within it, but they're not as impressive to me as NAG Tape. Still, I love them on cymbals, but not on full mixes for me. Also, if you have a little more to spare, the MLC from AlexB is 'perfect'. But the free ones that come with Nebula are also very nice, like 4KToHeaven. But still not as impressive as the MLC pack, I use it on drums all the time because it makes them sound more real. Well, I guess it's just about searching and searching more (which I also try) to find some more good ones.
Thanks for liking the impulses I made. They're recorded with the very same setup that I recorded my mix of the song with. About the placement, it's really easy on the ENGL XXL cabinet. It's really forgiving and near impossible to get it sounding fizzy. Still I'm not satisfied with my own sound, I should tweak it more (or try different microphones). On the current mix it just sounds a little too thin I think. Well, trying to get it better is only more fun for me.
I also think of reamping through my Marshall cabinet soon, should be nice too maybe.
*edit*
Also updated my mix again because it was getting too squashed, and also too much of tapesim harmonics. Well it's probably not that much of an improvement (if any at all). Hoping for some specific tips on what should be done better, still...
