So here's some delays on a guitar track.
8 bars dry.
8 /w Relay, some twisted rhythm, mangled with FX.
8 /w another setting of Relay, same theme, different settings.
8 /w Deelay, dotted 8th reverse stuff with diffusion, tape dust and a bit of modulation.
8 /w MFM2, 4 different delays, 2 pairs of crossfeeding each other, the feedback amount controlled by LFOs. Plus some filtering and stuff.
One might get kinda close to the Deelay within the HX universe, the others are absolutely impossible, unless you dedicate pretty much all routing options to the task, and even that would only take you to the vicinity of the ballpark at best.
These are the kinds of things I'd like to see in a hardware guitar MFX flagship.
Honestly, a lot of that sounds like old Sweep Echo effect from the M series era on a parallel track paired up with a reverb like Ganymede or Heliosphere feeding into maybe one more delay - all at high mixes parallel to the dry signal.
