I have an Electrix Mo-FX. I use a Mackie 1202. I use the Mo-FX in the effects loop of the mixer. This works well, allowing me to mix distortion/flange/tremolo/delay into any channel.
While this works well it takes up a lot of space. I’d like to get this all onboard the modular and get a smaller mixer.
The Mo-FX allows you to set any channel to effect the hi, mid, lo, hi+mid, hi+lo, mid+lo, hi+mid+lo bands. There is a tap tempo. The modulated effects can all be synced. It’s also stereo.
