Darkglass Alpha-Omega with Focusrite Interface

Hi all,

Recently bought a used Darkglass Alpha-Omega Ultra pedal with the intention of recording this through my Focusrite Scarlett Solo.

I wasn't getting great results connecting the Darkglass 1/4 output to the Focsurite 1/4 instrument input then plugging my bass to the Darkglass 1/4 input.

So I read on here I could connect the Darkglass XLR output and run it into the microphone XLR input on the Focusrite. I purchased a cheap XLR cable, connected the two devices together (See picture) but as I loaded up Logic Pro I got no sound from this connected method.

Anyone know what's up here? Or is this completely wrong?

Thanks
