I've decided I would like to try a Lexicon rack unit for my stereo guitar reverb needs. I own a Polara that fills the duties admirably now but I want to take it to the next level. The primary function of the unit will be provide stereo plate reverb. It may get some other use but my modulation and delay needs are pretty well covered. But I never say never when it comes to effects. The rack unit will be at the end of the chain and reside in the fx loop. I know there's some guys out there that do the same thing and I'd appreciate some insight on the different PCM options.
