Marshall TSL footswitch woes

Have to click clean twice to switch to other channels.

Had the same issue with these as well and well. Two Footswitches and soon another that’s aftermarket.

Will see how that goes

I had this issue with my foot switch for my TSL100 head, it was being caused by cracked solder joints on the back panel PCB, I removed the PCB and reflowed all the joints and I've never had an issue since then.

In the end, I had to just buy a new footswitch for the Peavey Renown 400. Sigh. Barely got to use it.
