The Eventide pedals are fully remotely controllable via MIDI, and are absolutely incredible. A stack of H9s is an extremely powerful combination, since you can change their routing dynamically (in mono they can flip between pre- or post- chain depending on the type of preset or your own determination, without rewiring), and because an H9 can be any major type of effect you want - pitch, modulation, delay, reverb, and certain combinations thereof too. These are immensely deep algorithms, each of them comparable to a full plugin, and you’ve got about 48 of them in each pedal, with customization, presets, remote control, automation, CV control (via expression input 0-+5V), gate for tempo, etc.
Edit: didn’t realize this thread was so old! Saw it pop up, thought I’d reply to a few things… wow. There are a ton of great reverbs out there, though, for all budgets and categories. If you’re not into menu diving but you want some of the depth and control that digital reverbs can offer, look for ones that are MIDI controllable and use a MIDI interface, that might save you some bucks and be a nice compromise between hands-on intuitiveness and the flexibility and depth of a good deep digital setup.
