Here's a quick comparison video between the Neo Instruments Mini Vent, Strymon Mobius and Fractal Audio Axe Fx II. Rotaries are played clean and with drive on in mono and stereo.
Routing for Mono:
- Guitar - Mini Vent - Mobius - Axe Fx II input
Routing for Stereo:
- Guitar Axe Fx II input
- Effects loop Axe Fx II - Mini Vent - Mobius back into the Axe Fx II
