If the HX Stomp is too much, but you like the thought of the "all-in-one" box, that you can use for guitar as well...
Have you considered the POD Go?
The models on it are all from the Helix, amps, cabs & effects, you can use IR's, you can use snapshots, but there are obviously some differences. No parallel processing, limited no. of effects to each patch. However, it's still a really flexible unit that sounds great.
