I think it's all wrong people discussing about racks. Soulscape where are you bro ?
Processors and most Clean Racks are all modelling stuffs. It's comparitively simple to model a delay, chorus, flange and things like that. Even entry level things like 505 has them all. But getting them to sound most natural and transparent and analog requires real hi fi algorithms, powerful DSP processors and a lot of things. High End Racks do that and get them sounding pretty close to analog. Rack sounds have totally a different feel. It's great when you want to play things like the smooth Jazz or even Metal.
I dont know what do you mean by low end racks. Rocktron Intelliflex, Alesis Quadraverb costs about $200 but there are a lot of pros using them. They are all clean effects rack. I have played through them and honestly I felt they suck in their effects. Their reverbs are great though. They sounded better than the $400 processor though. But most people using Alesis Quadraverb or Intelliflex use it only for Reverb. They can get separate racks for other clean effects. As far as I have heard nothing beats the Maxon CS9 Pro Chorus. The Chorus effect in these two racks I mentioned sounded like a Joke. Processors sound the same too. Processor v/s racks have their own pros and cons. You cannot carry your rack around and needs a lot of learning curve to use them at ease.
