This is a fantastic jack and although they cost a bit more, these jacks will save you hours over their lifetime.

The Right Angle SuperJack features a retractable spring loaded sleeve that shorts the inner conductor to the outer so you can test your lead very simply.

Just test for a short and you have continuity! This is the easiest way yet to test for lead open circuits.

Use a standard jack on one end and fit a SuperJack to your amplifier end and you're good to go.

The Right Angle SuperJack is awesome for effect pedals and any other application where a right angle is needed.

Super Jacks are sold in pairs.
