I am definitely using the reverb. The Plate and Springs are actually quite good, if you're willing to brave the menu diving and tweak them a bit. (I've never understood the appeal of Room reverb - adding an effect to throw the "clang" on top of your tone that some people spend tens of thousands of dollars trying to get rid of with physical room treatments?
I guess it's a headphone "realism" thing, i.e. "OK, now this sucks. Realistically." Otherwise, hello? I'm already in a room.)
I'm generally drawn to onboard effects wherever they're available - even if there's a
reasonable compromise - because I like to see what I can get done with as little board real estate as possible. That was the appeal of the Stomp, the QC, and now the ToneX. 90% of the time I could get away with ToneX and nothing else, but for the fact that I'd miss a delay of some kind.
