In the past I used a Digitech GNX 3000, currently using Zoom MS60-B. Would love to try the Fractal AX-8 or Helix, but I would only have a handful of places I would play them out. I'm not spend that kind of coin and putting it on the floor at a bar gig. I could do the rack thing, but then you are getting too large. My Zoom and MarkBass Nano gives me everything I really need.
