I don't quite like the location of the new buttons, but the idea itself is pretty awesome. This 6505+ footswitch has been modded, it now has two effects loops built in.
It was modded by CheeseBlocks Effects Pedals - Wall | Facebook ...never heard of them until now.
That is THE best solution for a guy using pedals in the loop... I would love to have this solution for a on the road rig.
