I had an Eleven Rack.
The build quality was great.
For higher gain distorted sounds, the unit was *very* noisy.
If you're talking a hardware unit, the Boss GT-100 is pretty nice.
Although it's not an Axe-FX or Kemper, it sounds better (IMO) than any other hardware based amp-sim (including POD-HD). Very convenient unit for direct recording... or zero volume practice
With the dual displays, the GT-100 is pretty easy to tweak/program.
Check it out (if you haven't already)...
