As Dugg Funnie said, example plox. Maybe we're addressing different problems here.
Though, IMO with reverb: Control the space of the reverb, something might not need to be in stereo - use mono, "less stereo" reverb. A good way to control this is using the free epicVerb plugin, if your reverb doesn't allow it. It's my favourite reverb by far. Before reverb, EQ the sound for a preferred dry sound, then put on the reverb and EQ the reverb. To me, the reverb is quite a mixture of feeling and presence. Make a very high passed or sometimes low passed, barely audible, but it will get that wide "hall"-sound anyway. Sometimes a bell in the 15 KHz and up area can help, but generally, if you need to heavily EQ the reverb, say +-6 dB, you'd probably wanna look into your reverb settings.
When dealing with stereo reverb, I usually cut pretty much everything below 200 Hz, and usually, it's more likely to be around 1 or 2 KHz, since I consider everything below mud in a lot of sounds, especially in busy tunes.
In some cases a stereo imager can do the job better, if you just want a wide sound. It's much more controlled. Delay is also a possibility. I rarely use delay, and could probably count the amount of time I use delay on one hand (Except for phasing effects. Echo-phasing is awsum
), though I've seen it recommended sometimes instead of reverb.
Also, less reverb.
