The Rocktron Intellifex is one sweetest processors i'v seen and I wouldn't replace it by soft verbs.
It does wonders for just about any instrument and acts as a multiple fx processor with hush, delay, pitch shift .. whatever. It's sweet. .. 24 bit triple converter with 64x oversampling ..
I wouldn't use my cpu cycles on reverb since my rackmount does it all.
Granted you have to take it one track at a time .. so the advantage lies in the plugin's court on that one .. but this particular rackmount unit is so reliable and flexible that i wouldn't trade it for 5000$ worth of plugins.
