You're all going to kill me for this

but here it goes
I recently replaced my bridge PU in my Ibanez RG7321 with a dimarzio evo 7
well it was all fine and dandy until a few days later it started buzzing....bad.
I went through the wiring and nothing
so I removed the tone knob to see if it'd help
it didn't....well it did since I don't use tone knobs anyways
anyways I have no clue what the problem is with it
I mean its like it isn't grounded, I touch it and the buzz goes down exponentially but not all the way.Any ideas?
and yes the ground wires from the PU's are grounded to the volume knobs

I may be wrong but that sounds like a bad idea.

Perhaps it could be that your volume pot fried from soldering to it and getting it too hot. Just a thought.

perhaps your bridge ground came loose. even just a cold solder can cause tthe buzz. this means it can look like the wire is still attached and physicaly it is,but its not conducting or passing the signal/electricity.

You ground stuff to the back of pots, then to the ground on the output jack.

Not to mention to the strings via tremolo spring hooks or TOM pole.

you can try touching the strings. if the buzz stops when you touch the strings you have a bad ground. now you can either use a voltometer or resolder everything. you dont actually have to resolder,just heat up the existing solder to get a better bond.

Pickup Ground wire => Soldered to back of volume pot => wired to Ground on output jack.

If you're missing the last one then you don't a ground in your circuit.

Since ou have an RG7321 I'm gonna assume you have a 3 prong jack which is mono that looks like the one on the right.


The wire from your switch (live) goes to the largest prong and the ground goes to the smaller prong which connects to the outer rim of the plug.

you have a break in the line somewhere bro. when youchanged pups did you just twist .... together or solder? did you splice to existing wires or did you remove the old wires and solder the new pup into the switch?

Usually on low end Ibanez guitars I always replace the electronics as they are very cheaply made. The switches always end up going out on me. YMMV however.

I don't mean to hijack the thread, but I've been having a very similar problem with my 7321. I noticed the humming after I removed my tone pot. (This was also after a pickup change, but that was done professionally.) The grounding all seems to be properly connected (jack, volume pot, bridge, and switch are all connected to each other; tested with multimeter), but there is still a loud hum. It pretty much goes away when I touch the sleeve of the plug.

I've tried everything, short of adding extra shielding, but nothing has made a difference. Any ideas?

ok now that I removed the pick up selector and the tone pot I now have no volume even though I have a volume pot and now I have less gain as well.....this is pissing me off
I want my volume knob and Imma ask whats his face on here to make me a sustainer as well since I don't use my neck pick up. but back to the issue less buzz but still there now theres less gain and no control on the volume....seriously what the flying mother........its pissin me off

try this bro! wire the jack straight to the pup. that hot jack straight to hot pup,neg jack to negative pup. now link your trem ground to your negative wire (where you hooked the jack to the pup ) no switch,no pot. this should be full blast on that pup with no buzz. does your pup have the single coil wires that have to be wired together for full double?
