Hi y'all - I'm looking at one of the three options to become a new "preamp" of sorts in my chain. I like what I've heard of all three pedals - the EP and RC seem sort of similar to my ears, with the RC offering more controls. The EM Drive seems pretty simple, but adds a lot of punch and sparkle. Whatever I choose, it'll be set as a clean "thickener" to fill out some space and harmonic sparkle. What are your thoughts on the three in regards to what I'm using it for?
