Jack made incorrectly... think it's Switchcraft?

    I had one of those in the late 70s.
    Granted, it was late 70s, but I honestly don't think the design has changed.
    It was an added failure point, and really not reliable.
    Neat idea, but I was sorry I bought it, and the oversized plug case was hard to get a grip on to remove from the Strat.

    Wow. Didn't realize the design was that old. I hear ya on the failure point. If it ever does happen, I'll either just swap on a new end just like what's on it or just use their standard jack instead. Since they're solderless, it should be fairly quick to swap a new end onto the cable.

    The old ones were huge... barely fit into a Strat. They had a small pin next to the jack pin that made contact when depressed by the jack sleeve.

    Especially when the wheel is just one thick spoke and a rim and works reliably for thousands and thousands of miles.

    Looks to me like the threaded part is too long, keeping the plug from being fully inserted.

    there is a long version and a regular one. Maybe the components got mixed up at the factory.


    I also like the puretone ones, especially the stereo version for active pickups.

    So, finally pulled it back out. It's stamped Switchcraft.

    So, either it's an all-in forgery, or it's an incorrect combination of parts per @Wayne Adams 's post.

    Just a note on this... only one electrode actually grounds and sparks, no matter how many you have. The odds of more than one being of any value are minimal.

    The extra contact on the Puretone might actually help though. Both can be connected and if one skips a beat on the connection, it will be maintained by the others. So, I see some value in them. Of course, it could be a problem solved by simply using a quality jack.

    For giggles, Alfa Romeo used to use these in the 1.6L (maybe the 2.0) late 60's motors. $12 back in the day, $30 now. I don't think the extra electrodes matter.

    That is unfortunate. I assume you put in a proper replacement?

    Probably heresy, but think somebody oughta reimagine the 1/4" jack, or least give enough thread so you can double-nut the darn things, which inevitably loosen, it seems. I think jacks are the most failure-prone thing about an electric guitar aside, on occasion, from my aging fingers.

    I love Alphas, even though they are the only cars less robust and reliable than British cars, which I also love. I also like cheap guitars. Am I ill, maybe a touch masochistic?

    (Yugos, I know, and Renaults, but one can only think so many painful thoughts in a given span of time.)

    See my other post above. I managed to find a compromise bend that allows it to work for them time being. Amazon credited me without a return so no cost (wasn't much anyway). I'll order from someone else when I place a larger parts order soon.

    I have one just like that in my box of parts. It's not a Switchcraft, and I'd put odds at 10:1 that yours is not a Switchcraft either.

    Exactly.
    The 4 contacts make for a more secure mechanical connection to the plug, firmly gripping both the tip and sleeve from both sides, rather than relying on a single point of contact on the tip, and the spring pressure forcing a cant into the sleeve to make contact on the base.
    It is just overall a better design, without added complexity that adds potential failure points.

    Spark plugs? On any given firing, only one ground electrode provides the path, but multiple paths add resistance to fouling, and also keeping in mind that the chamber is not a calm environment that contains only air... there is a swirling mass of air/fuel in there, and not all points in that mass may be stoich.
