A/B box could do the trick yup - i have one actually... food for thoughts...
As of now, my current live rig in progress is:
HXS XL + 2 exp pedals + 3 loop pedals + 1 Boss OC3 + 1 MiniPolytune (+Cioks DC7 powersupply)
all fitting on a DIY 14x10" pedalboard
Adding MG2+iPhone+iRig+A/B box is still more stuff prone to failure on the gig.
As for the Helix: no, It s much too BIG!!
Granted it will bring a lot of solutions, although ike many here, my goal when going Helix is to downsize my rig - smaller, lighter, simpler, easy to trouble-shoot onsite, faster to set up...
I tried HeadRush MX5, regular HX Stomp + Midi switch, and now the XL - so far the best solution.
Any device is heavily vetted before being included!
- ideally i m aiming for all-in-one-box type of solution ;=)
