Re: Mystery pedal
I remember two pedals from the 1970s, the Ghost and the Speed King.
The footplate design is more in line with what Ludwig was producing in the 1990s. I'm guessing this is a Rocker/Modular bass drum pedal. The LM-414-FP 1988 is very similar but has a different footplate. It could have changed to the 90s style footplate in subsequent years.
