A very high quality- Full sized strap-pin stereo output jack in sumptuous GOLD. This is a great piece- We drill a 7/16" holed centered on the existing endpin hole- Then VERY CAREFULLY use the big 'ole screwdriver to thread the unit into the end block. The result is a totally solid and rattle-free-for-life installation.
I've sold and installed a ton of these- and they're flat-out great. Totally reliable and really nicely made! No crackling and loss of contact- a real reliable QUALITY piece.
