This is part of the REDactive solderless "Plug-N-Play" wiring system.
The heart of the Plug-N-Play system for any 3 Pickup installation. Insert the tinned leads for your switch into the quick-connect block and plug the components in for active pickups, or plug the wires from your PASSIVE pickups into the block and use a plug-in switch for ACTIVE installations. Brilliant and simple.
Comes with two pieces of velcro, pre-installed for easy installation and removal.
While this is designed for solderless installation solder pads are provided for normal discrete soldered wiring.
