This is the Spec 1 version of the plate that fits over the electronics route on the back of many arch tops.

There seems to be a few varying specs to the humble control plate cover and by the look of things, it purely comes down to a lack of real standardisation in the industry, which, quite bluntly, makes identifying them a bit of a pain.

Best advice we can provide is to check the specification diagrams under the Technical Specification section.

Once you find the matching plate, they’re a pretty basic part, again, similar to the switch cavity plate, often damaged or lost when working on the electronics of a guitar.
