You might try to dip (wide Q) a little around 2-4k to see if that helps on hat/cymbal 2 db should really be enough… also roll off starting around 16k. Just play around with those frequency cause im just guessing Did you use a limiter on that channel?
As far as Trumpet goes I can turn you on to 2 great players They won’t be free but they are worth every cent and from what I hear your music deserves the best. Wim is of coarse in a class all by himself and simply one of the best players I have ever heard! PM me if you want their contact info.
