Help! NGD buzz but not fret buzz?

King85

Finally got my Charvel DK24 which my gf had got me for Christmas but had been delayed due to supplier issues.

I thought I had just solved this but sadly not.

There is a buzzing of something resonating when playing an E note on the highest three strings 12th fret E, 17th B,etc. I initially thought I may be coming from the volume knob area but my gf listened closely and thinks it the bridge area.

I screwed the trem arm in which I hadn't yet done and it went but then I noticed it had just moved and now rattles when a D note is played.

Any ideas what would be resonating to cause this?

Edit - Actually solved now. one of the adjustment screws for the B string saddle wasn't quite touching the bridge and this was causing the buzz. Sorted now though if  @Bridgehouse ;;@Jalapeno ;;@Roland could delete this I'd appreciate it. Thanks.
