I'm adding the pitch shifter after the amp but before the dual cab combo. It's pretty much the thing that's supposed to generate the stereo before I send it to the delay/reverb effects. So far I've been using the Helix through headphones only. I'm not talking about bouncing around longer delayed signals like 1/8 and 1/4 notes. To give you an example what I'm using so far on the Helix to generate the stereo spread : I put in a dual delay behind the amp, set the left time to 9.5ms, right time 0ms, no feedback left and right, left and right mix both at 50%, 0db level, 422Hz low cut, 4.1kHz high cut, modulation off. This works ok although the effect is not quite as impressive as the pitch shifter in AmpliTube and I was wondering if there's a better way to achieve this effect.
