Well, I was trying the different things you proposed in your posts, and I reached like 90% of the goal by compressing the snare.
I put a compressor (Vcomp) after the reverb (I had to change the algorhythm from plate to a sorter room, because, once the compressor kicks in, it ends up with a huge and uncontrol reverb) with fast attack, fast release and like 3db gain reduction, and it worked perfectly. Now I just have to bypass the compressor in some fast riffs!!
Thanks a ton for your help!
