You can alway count on Switchcraft, there are cheap units out there , and are not worth buying, these are worth their “salt”

I've been servicing electronics professionally for over 35 years now, and in that time have replaced well over a thousand jacks i'm sure. I have always replaced cheap, inferior jacks with high quality Switchcraft jacks, because nothing sucks more than having to explain to a customer that their amp failed again during their show because I was trying to save them 50 cents by using Chinese garbage. They're so beautifully made, that even Neutrik hasn't been able to improve them.

SwitchCraft is the best you can buy at the price from Antique Electronic Supply. They have always came through with years and years of service. Problem free, maintenance free. I have no reason to use another product, The jack does whats suppose to. Install and forget about it..

You can't miss using Switchcraft. And at a decent price you can't go wrong.
