Hi there, I hope you found a way to use the headphones with the Supro Blues King 12. I've got a Supro Blues King 8 and since I wanted to use my headphoes together with my Blues King 8, I bought a 6.35mm Mono Plug to 6.35mm Stereo Jack Adapter. This adapter I connected to the Line Out on the Blues King and used the Master knob on the amplifier to change the volume. It works great! I believe that a 6.35mm Mono Plug to 3.5mm Stereo Jack Adapter will work as well. Have a look at https://www.cmple.com/6-35mm-mono-plug-to-3-5mm-stereo-jack-adapter/ to have a look what the adapter looks like.
