Grounding issue??

Hi all. I was wondering if anyone has any suggestions for a little problem I noticed. I'll apologize now for what's probably a newbie question, I've only been at this for about 6 months.

 

I have a Squier Strat that I am currently playing through a borrowed amp. The amp is an old Fender Musicmaster bass amp(my buddy loaned it to me to play my acoustic-electric through, he said a-e's sound pretty good through bass amps). With the pick-up selector switch set to positions 1,3 or 5 I notice that there is some "buzzing" or humming noise that gets louder when I touch either the strings or the bridge saddles. Is this normal? Am I just noticing the difference in the single coil pup vs humbucker? (This is a 3 single-coil guitar, not a fat strat but I know the middle pup is reverse-wound so that positions 2 and 4 are similar to humbucker style)

 

I trouble-shot by plugging the guitar into a Zoom effects pedal and listened to that directly through headphones and no similar noises occured. Seems to be the amp. This is an old tube amp so I wouldn't be surprised if it has "bad" tubes. Would that cause this?

 

Sorry again for sounding like the newb that I am.

If the buzzing gets louder when the the strings are touched, it could be a grounding problem (but I'm not certain). The buzzing should diminish when the strings are touched on a properly grounded guitar/amp combination.

 

Why don't you try it on another amp and see if it does the same thing?

Thanks a lot for the tips guys. I'll have to wait for this weekend to try the guitar with a different amp since this is all I have access to right now. I'll definitely look into some of the tips discussed on the videos too.

 

One thing I learned from the video link is that I may have spun my input jack around and dislodged the shielding wire inside. The jack is always loose (keep meaning to put a lock washer on there) and I will gently spin the nut tight with my thumb, I may have spun the wire off inside.
