Yeah pretty much.You're trying to run an entire band (guitar+bass) through one unit, right? IN that case, yeah the Helix would nail that. It's got a shit-ton of IO that it's possible to have one of the 100000 inputs to accept a 2nd instrument. Plus the ability to run to run two independent chains.
I might keep the POD for the other guitarist. The bassist changes sounds and is kind FX heavy. I only play twice in the set but I need a rhythm and lead tone.
Technically I could run all three of us but we'll see what happens. I also need the ability to run IRs I have..and the Native plugin obviously helps a lot. So it just seems like the best choice.
