Rocktron Midi Mate & Boss EV-30 Help

[Abstractsanity]

Looking for some help setting up a Boss EV-30 expression pedal with my Rocktron Midi Mate and Axe-fx 2.

I would like to run the pedal through the rocktron instead of having to run a cable all the way back to the axe-fx but I cant seem to get the axe-fx to recognize the pedal through the rocktron. Any help would be greatly appreciated!

I used a Rocktron Midi Mate with my AxeFX2 for quite a few years. I also ran the expression pedal through the midimate and ran into issues. Took a while to sort out but the long and short is that the midimate is not a 'straight thru' wiring from the Boss expression pedal.

The tip of the rocktron plug is wired to the ring on the Boss pedal plug

Definitely some useful information, thanks! I think the issue must be with the rocktron.

Thanks! There is a switch on EV-30 to switch polarity, would that fix the problem without having to rewire the cable?

Unfortunately you'll need to rewire the cable because it's not only the tip and ring that need to be rearranged. The sleeve is also affected.

Just follow the sketch I posted and it should work fine.
