I got a tip from Bitflipper recently about putting a stero panner on the reverb? It's a pretty cool technique :-) You have to be subtle about it? But the sweeping pan 1  2  3  4 (for example) on the vox vs. 1 2 3 4 on the instruments (all in time w/the song) Can add a pretty cool effect that the listener doesn't necessarily perceive? You hear it, but it just "sounds good?" :-)
 
Thanks Bitflipper.

You mean automating a reverb so it moves position over time? Or like you can do in a convolution reverb where the tail end actually fades into one direction? Or by putting the verb to the right side when it's panned to the left?

I don't quite understand which technique you're referring to...

I remember reading the convolution one in a post recently, might have been by bitfipper. Have not tried it but I'd love to some time. Would be really cool to send the tail off to one side which could allow you to have a really bit long reverb sound, but then pushing it quickly to the side could stop muddying things up. You could even use two slightly different verbs on a main vocal, and pan one to the left and one to the right, so your vocal sounds really wet, but the verb quickly spreads to the sides and leaves the centre dry for the subsequent vocals to follow. Damn, I really like that.. That could sound amazing.. That could really work well on a nice ballad...

Yeah, I'm talking about wiggling it from one side to the other? Like a crockadile tail as it swims through the water. :-) It's a cool effect.

I suppose this is what I do with Sonitus delay ... except that I only use one such delay buss (for tidiness sake): 1/3 LT, 1/8 RT or such ... I don't remember.

Such delay works 'cleaner' than 50msec pre-delays on my plate-verb buss.
