The ashtray cover is a very simple design – it is pressed from steel and attaches to the bridge by simple pressure. In order for this to work there must be something for the cover to grip, which is why there are no covers made for modern flat sided bridge plates.
The cover can be fitted by one of two methods – sliding on from behind the bridge or pressing on from directly on top.
The slight flaring at the front of the cover allows fitting by sliding on from the back of the bridge – when it hits the narrower point the cover bends out slightly and provides a firm grip to the bridge. Be careful using this method as it is easy to scrape the finish behind the bridge.
The rolled edge of the cover allow the same result when fitted by pressing down from directly above the bridge.
If the cover is loose, which can happen over time/use, simply squeezing together the narrower points of the cover will enable a tighter fit. It can take quite a squeeze, so make sure to have a firm grip so it doesn’t fly out of your hands!
In the picture above the Fender Ashtray Cover is firmly fitted on a Wilkinson WTB Vintage Telecaster Bridge but of course will fit any Fender vintage style bridge plate or any bridge plate made to Fender vintage specs.
(That’s a lot of words for a very simple design!)
