My amp buzzes when my strat's on the bridge/neck/middle pickup but never when 2 pickups are on at once.

eg. bridge and mid/ neck and mid.

What could be causing this
My setup

Fender Mexican strat Sunburst/maple

Cort Solid top Accoustic, fishman pickup

Marshall JCM 900 Dual Reverb 50watt Hi Gain combo (upgraded to Celestion G12 M Greenbacks and Class A conversion)

1985 Fender Telecaster 62 reissue (with some modern parts on it)

That is the curse if single coil pickups. Just one on will get a bunch of RF interference. Both on have the cancelling effect of humbuckers....hence the name.

Hmmm so theres nothing I can do?

It even does it when I'm playing and it's very loud

It actually still does it when both are on at the same time but it is a lot more quiet

There are things you can do.

Try to sit away from things like tv's, computers, florescent lighting if you can. Those are where a lot of hum will come from. You could shield your guitar with shielding paint or tape. Those are the two biggest things you can do.

If you have the money, you could get shielded wiring installed in your guitar. But the paint and tape would probably take care of the buzz enough to where it's not so bad.

I had this problem to I have all my guitar stuff in my bedroom. Where I have both my tv and computer my amp didn't buzz unless I had every thing turned up all the way. Sure I could just turn it down but then what's the point. So I bought a Pickguard Shield it's easy to install and worked very well. When I was wrighting this I started thinking don't starts come pre shielded? So this might not help sorry.

that and make sure your grounding on your guitar and wall outlet is good
Let the pretend take over
And that season be the first
Shadows we're in become us
So we set up interspersed
Between here and away
Become your space every day

some amps like Peaveys have a ground switch on the back that can lower the buzz.
"Oops, did I say that outloud?"
