Switchcraft #12A - 1/4" Mono Jack (with tip shunt)

As others have commented, the Switchcraft tip shunt jacks are quality and my preferred choice for amp builds. However, occasionally the ground tab on a new jack will bounce back against the hot (tip) tab, after the cable is plugged in, causing a short in the signal. It's an easy fix -- just bend the ground tab outward gently so it clears the other tab. But if you ever find an input or output of your amp shorts out intermittently, this may be the problem.

The quality you expect at a good price.

No reason to skimp on quality at that price point.

The best jacks money can buy. Good jacks are very important.

Quality as always
