The CLA effects plug is really geared to modern overused vocal stuff like telephone/distorted voice and such. It has nice verb, delay, chorus but IMHO is the weakest of the CLA bunch. Don't get me wrong, I really like the CLA set and when you want that "drop everything out and shift the vocal to "telephone" thingy" the effects plug does give it to you perfectly. It may sound crazy coming from me but I'd keep my $46.55.
My tout would be to bite the bullet and get the JJP set. I'm finding it more and more useful since I got it.
There is a tremendous amount of tweakability with these sets...especially the JJP... and they aren't just stock presets...you actually have quite a bit of control over many different aspects and effects within the chains.
