Hi guys a quick question of Gretsch bridges. I've just set up my 5120 which I bought about two months ago and I had noticed a kind of buzzy rattle very similar to fret buzz which I actually mistook for fret buzz when I first brought the guitar home after buying it privately. The neck had a very bad neck bow so I dismissed the rattle as fret buzz but with patience I've managed to coax the neck to pretty much spot on with regard to action height with neck relief set at around 8 thousandths of an inch without any fret dressing or overly high action and it plays very well indeed but the rattle still persists and I've discounted fret buzz as a possible source so it seems it's the bridge which is the issue. It's not horrendous or anything like that, but it's 'there' and it gets to me. Is this a common fault with this type of TOM bridge fitted to Gretsch models or am I just unlucky or even overly sensitive? I recently replaced a similar type of bridge on another of my guitars with bridge rattles and I've heard of various solutions to solve rattling bridges of this type including using nail varnish to stop the screws moving but that would make it very difficult to adjust the intonation in future so I'm maybe looking at stripping and servicing the bridge and packing it with something along the lines of Vaseline to deaden the unwanted rattles/vibrations. If it affects the tonal response from the bridge I can just flush it out with no I'll effects and find another possible solution. If I can't find a solution to the rattle what are the best options with regard to a replacement bridge for 5120 or a possible fix for the rattle if anyone has experience of this.
