If not grover titans, what would be on that bass? The remaining tuner on that bass has the same shape as the Titans used on T-40s, Patriots, and other basses of the time period
That is a good question for Tim. I have seen some 80's Foundations that have tuners with stamped keys and 4 mounting screws like on most Fenders. I don't have any idea of the brand and model that was used. The picture looks like a Grover Titan, but it blurry enough that it could be something else.
Speaking of Grover Titans. The current production Grover Titans have 2 mounting screws that replace the pins on the older model.
