After doing a few songs I noticed thafter applying Reverb, everything in JABB sounded muffled, and so i found a good setting that is now my Big Band preset. I work in Adobe Audition, but you can mimic these setting for any EQ.
this usually gives me a very bright, punchy sound for the Drums and Trumpets, which usually sounds good. I also raise the bottem end to give the bass little more life and volume. Hope this helps some of you wondering about EQ.
