Difficult to see Stu but you may have connected your output jack ground to the ring connection

If you put a jack in like the image below and trace the connections round to thier solder lugs

The ground lug connects directly to the sleeve like this

Your IN jack which I can see is correct, just an FYI if you’re not using a battery you can use mono jacks for both in and out I notice you have stereo for both which are slightly more expensive and welcome to the forum
