@krusty4president If you want big reverb, the nature of the sound you put through it makes a huge difference. Some sounds really don’t lend themselves to cavernous reverb, especially ones with a sharp attack. If your filter envelope has quite a spike on it, there can be lots of harmonics in there that reverberate in a rather clashy way that doesn’t sound good to my ears. If you have a long reverb set for your kit, it’s safer to reserve it for the tracks that have sounds with a softer attack and maybe not too much bass.
Also worth playing with the Hi and Lo Cutoff in the reverb. (This goes for the delay too.) Roll off either, and that part of the sound spectrum will decay more quickly. This is handy for stopping the mix becoming muddy. e.g. if a sound has lots of bass harmonics, rolling this off can allow the other frequencies to reverberate (or echo) away nicely without congestion at the low end.
Same goes for a very toppy sound - roll that bit off to stop the mix gathering tons of HF mush.
The really tricky bit is getting a reverb that sounds good for ALL the tracks you want to use it on:-( Some compromise with decay and cutoff settings may be in order. In 2000 I bought my Supernova II with its multi-timbral FX. It still feels luxurious all these years later!
