If you want to run all of those analog effects in separate chains you want the full floor unit, plus you can name the FX loops and read what you are stepping. Also you can switch in or past your Vox preamp in 4cm (or add another amp for a 7cm in stereo) and easily run a bunch of pedal loops, the Vox in 4cm, an FRFR, and go into a mixing board/computer/PA at the same time.
