Which rack unit is the best for live spontaneous shows with the most versatile user friendly settings? The unit needs to be capable of: Full bypass, distortion, wah, reverb, envelope filter, some bass amp/cab modulation, various electronic/spacey effects, synth, delay, ability to mix effects together. Must have a floor board (of course) Some units I have in mind are: Bass Pod Pro XT, Rocktron Blue Thunder, TC G-Major, TC G-Force, Evandide, Roland SE 70, Boss VF 1. Out of these I have only tried out the Pod. I will be putting the unit through an Ampeg SVT 4 Pro. Also, this will be my first rack unit! Any feedback/suggestions are greatly appreciated.
