I bought the Cabzeus Stereo....it simply didn't work with my Midi Rig. Henry was very gracious with his time, sent me a replacement.....he tried....but with no explanation as too why.....he simply concluded that it wouldn't work with my rig. I'm running an ES-5 and controlling a Jackson Audio Bloom, OD-200, MD-200, Source Audio Collider and now a Walrus ACS1 with it. No issues. The issue with the Cabzeus Stereo was in the presets and Midi operation. They just flat out didn't work consistently and would suddenly either go silent or suddenly produce a loud hiss.
