I fuuuuuuuuckin’ love this pedal. Like, it’s permanently wired into my mixing desk, it’s arguably the best reverb I’ve heard. It’s fantastic. It’s pretty easy to change patches, pretty much like any other other pedal with presets. You select from the patches you’ve chosen for each bank, one for channel A and one for B. As far as combining them, it’s simplest to just play about in the editor, SpecLab. You can’t have A and B on at once, so can’t set a reverb on A and a delay in B, but you can combine a reverb and delay into one patch, and then set that as A or B.
The depth of the options scared me at first, but it’s not actually that complicated. It is, however, incredibly controllable and versatile. I’d recommend trying one out if you can, because it’s a bloody expensive pedal and you’d want to be sure that you get on with it, but its resale value is pretty bulletproof.
The main problem with it is that your sound-man mates will try to steal it for gigs, it makes for such good outboard
