Let me begin this by saying I LOVE my Helix!!! It's awesome and I'm so thankful for Line 6 making such an incredible unit!!!
But, if they make a Helix XT (or Double Helix ðŸ˜). I want the top and bottom paths to have double the DSP. Two exp pedals built on. 6-8 more footswitches. Touch screen display. An algorithm that completely smooth out the spikes in volume and timing warble when switching between drastically different snapshots. Input and output meters. A dedicated knob for Time (BPM Knob) that can be disabled for live play so you don't bump it.
Pedals:
A true polyphonic pitch shifter update for the Dual Pitch.
Modulated Reverbs
Amps:
Boutique amps like Jackson or Morgan
Just the little things...
I really do love the Helix!!!
And even just the 4 DSP Chips would be great!
