Hi. I got a Squier Strat(affinity series) which is old, but it´s still in pefect conditions. I also have a fender frontman which I use to think that was broken because it's always making this buzz, annoying sound. This week I got a brand new Roland amp, a Cube 40-GX. I tested the amp on the store with my own guitar and guitar cable and the amp had no buzz or any other annoying sounds, actually it sounded beautiful. Then, I tested the amp on my house and it sounded horrible: all the buzz is back. Also, the buzz turns low when I touch a metal part from my guitar. Also the buzz tends to low down when I select the neck/brige position or the lead/middle position. I read that it may be a bad ground conexion from my house, but I plugged and amp in every posible outlet, and the problem persist.

What is the problem and how can i solve it?

You have electrical issues in your house causing the buzz to be picked up by your guitar.

Two choices:
1. Find the wiring or lighting problem and resolve it. (bad fluorescent fixture?)
2. Use a guitar with humbucker pickups.

It's the earth connection to the bridge of the guitar.

This.

Open up the back cavity plate and check for a wire that should be sticking out near the claw and the springs. If it's disconnected, that's your issue. Either take it to a shop to have it wired back or do it yourself with a bit of solder and a soldering iron.

Hi, thanks for the reply. Can you tell me how using hambuker pickups could solve my problem?

Process of elimination:

You have already tested the guitar and amp together at the store- no buzz. Your guitar and amp are fine. Somewhere in your house there is an electrical problem: failing florescent light ballast, failing fridge compressor, mis-wired outlet etc that is causing electromagnetic interference (AC hum). Find the problem in your house and fix it. Unplug all suspected appliances and re-test your guitar. When the hum stops, you found the problem. I've had this problem many times on stages with cheap lighting dimmers. Sometimes we can shut off the dimmers, sometimes a humbucker guitar is the only solution.

You can confirm this by taking your guitar and amp to a friends house and test it again. No hum there? It's not your guitar or amp.

You can't, but it would be nice if your dad had a professional fix the wiring in the house for the sake of safety.

That's almost certainly your problem, but aside from that, just be sure you're not playing near fluorescent lights, your laptop, etc.
Feel free to call me Kyle.

Have you actually put a meter on the earth wire to see if it has actual connectivity rather than just doing a visual inspection? It may be broken where you can't see it.
Actually measure the resistance between the back of the pots and the bridge. That's the only way to know if it's intact.
