Connecting Digitec Trio+ and Boss OC/5

You can use it Infront of your Kemper input or use the effect loop when you wanna use for example compressor of the Kemper first.

For the digitech trio you can wire it up using the kemper's aux in in mono or stereo depending on your setup. That way it wont run thru your effects. the oc5 should go before the kemper so you get the pitch pull straight from the guitar. So Guitar into trio, clean out into boss, boss to kemper. And trio outputs to aux ins.

Scratch that, was thinking of the sdrum. Sorry.
