I made up a few of these for some cabs I was refurbishing.

This is modern speaker cable that has been twisted and cut to a 2m length, perfect to replace the crappy wiring / switching that marshall currently use in their cabinets, while this does look like the vintage stuff the plastic outer layer is a little thicker than the vintage stuff

The sale includes a brand new Neutrik mono jack socket, the last photo shows this installed in one of my cabs(cab not included in the sale obvs) very easy to install, some wire cutters and a soldering iron and your good to go!

Anything else just ask.
