hello tb'ers

I bought a squire modified vintage fretless bass a week ago. This bass is amazing for the price, I'm in love with the thing.

anyways, it has a nasty buzz... not just the "turn up both PUs and it goes away" sort of buzz, it quite bad & sounds like a grounding problem.

Anyways, I took the control cavity cover off & found that the output jack only has one wire on it. should the ground not be hooked up to something? there is a dab of solder on it like there was a wire on it, but there is no loose wire in the cavity.

does someone have one of these basses (or any passive squire) who could have a look at theirs & let me know how it's wired? i can add the wire myself if needed, I just know where to attach it

thanks!

If the only wire going to the output jack is the wire running from the tone control, then yes, there is a problem. The output jack should be connected to a wire that connects to the bottom of the bridge through a small hole in the side of the cavity.

that's sort of what i assumed. it does sound like a grounding issue because the buzz goes away when i touch the strings...

there actually is a wire coming from the bridge, but it's attached to the casing for the tone pot. which, i guess sort of seems right (because that's usually grounded), but there is nothing attached to the ground of the output jack. here's how it's currently connected:


output jack ->tone pot (also connected to the pickup vols)

the tone pot wiper is connected to it's casing through a capacitor
casing is also hooked up to the bridge wire


...how *SHOULD* it be wired ??

I thought it was pretty standard on a jazz to have only one wire to the jack, with a ground from the top volume to the body.

But there are many ways to ground a bass - have a look in the setup folder, there's lots of ideas and different solutions.
