Fender Jazz buzzing

[Garry Sharp]

My new (1 month old) Fender Jazz has just started emmitting an electrical buzz, which gets worse when the treble cut is fully open (i.e. max treble) and when I touch the strings. I could take it back but that's rather a hassle and as I can use a soldering iron I wondered if there is an abvious cause / solution? I'm guessing it's an earth problem but am not terribly knowledgeable about guitar electrics. Any suggestions? Thanks in advance.

Looks like you have a bad grounding somewhere.
Go check if all the ground wires are OK (none broken or bad soldered) and we'll see later.
Good luck,

Yeah, that's what I thought. Had a good look and poke around under the plate and couldn't find anything looking dodgy. Think I need to get a pro to look at it. Planned to start recording tomorrow evening
