Yeah, I have always loved rack stuff. I still have the Axe II, MPX-1, G Major 2, PEQ2200, Intellifex, Replifex and a Synergy rack. I have a few poweramps and a Samson SM-10 rack line mixer to run all the effects in parallel.
However, having pedals like the SDE-3000D and 2290p, I can appreciate why the world has moved on. Having more surface area for buttons and screens and such is nice. The rack is kinda funny that you have 19" x 10" of blank space on the top, and then like 1 inch for the screen and buttons, lol.
