End pin plug, NoJak, ebony

What do you do if you want to 'reinstate' a guitar which has previously been fitted with a pickup and now has a 1/2" diameter hole where the strapjack was fitted?

One option is the clever 'No-Jak' end pin. An ebony pin slides into the 3/4"-long plastic expansion sleeve, and adjusts from inside the guitar with a black metal screw. 5/32" (4mm) Allen wrench required. The Allen-adjustable expansion sleeve gives a secure fit. And if you ever decide to plug in again, swapping back to your strapjack is no big deal.
