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

Good enough for the military, good enough for me. Go Switchcraft!!!

it works!

This is the input jack that all others are measured against. It's sturdy as can be, will last years, and not prone to oxidation. Beware though, it does not come with a toothed washer - that needs to be purchased separately (NextGen product SKU NG-GPS-B000NSDS6C). Without the washer, it won't make solid chassis ground contact, and will want to spin.

switchcraft 'nuf said this is the stuff and this is the place to get it happy to have a supplier near to me

I can always count on these guys for having what I need and if not in stock finding product. This jack is used on Fender amps particularly the Blues Junior.

GOOD PRODUCT WORK PERFECT

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.
