Technically there shouldn't be any trouble matching these but I do notice two things:
The Amp is pictured on a workbench. Doesn't have to mean anything but could be that the seller has tinkered with it.
The settings on the amp are a recipe for low definition low end drone with both VLE and VPF at noon with the bass cranked. Furthermore it's going to disappoint in power with the gain set that low. Set it to where the Clip light just comes on when playing the loudest notes, then roll it back a tiny bit.
Maybe add a dollie (plank on wheels) for that cab like it's sitting on in the pic, if it's not sold with that included
