There are a decent number of people still using Yamaha Magicstomps (2001, based on DG, UD Stomps and SPX). I have one in the loop of my HX Stomp. It stays in one preset (8 band parallel delay), and I wish it had DIN MIDI, but I'm going to have to do 3rd party mods to integrate it with my MIDI controller. Still sounds amazing, and it can't be replaced by anything else. It runs on 12 vac, which isn't good, and there are some issues with these in general, mostly due to being a 20+ year old product that runs hot. I keep hoping Line 6 rewraps the original algorithms into the HX architecture, but they haven't quite done that with the effect I use.
