The "Vintage Jack" compared with a typical endpin.
K&K includes an 1/8" to 1/4" adapter (not shown) to allow use of a standard guitar cable plus we offer the vintage jack in a solderless version that is available only at K&K..

The "Vintage Jack" is made by Tapastring and lets you enjoy the benefits of having a pickup installed in your instrument without having to worry about damage or loss of value. The "Vintage Jack" replaces your existing tapered endpin to make your instrument pickup ready -- NO DRILLING REQUIRED. Tapastring has incorporated a Switchcraft 1/8" female output jack into a precision machined end pin. Now you can install pickups in your instrument without having to drill out the end pin hole or use some other less than ideal connection system.

A "Vintage Jack" is available to fit most guitars, mandolins, and similar instruments equipped with standard taper fit end pins. The "Vintage Jack" is securely retained by the taper fit of the mating parts -- no adhesives required.

More information on the Vintage Jack from the manufacturers page.

Please note that a small 1/8" connector will not have the same reliability rating than our standard 1/4" endpin jack. This is because of the nature and size of the 1/8" connectors. Tapastring uses the best connector that is available on the market today but due the smaller springs, contacts etc inside a female 1/8" jack it will not provide you an equal trouble free live span like a 1/4" connector does. Even though the vintage jack is setup stereo, we officially offer the vintage jack for passive Pure pickups only. For dual source systems and active battery powered systems we strongly recommend using the standard 1/4" jack.
