I'm not entirely certain whether pedals are on-topic, but here goes.
One of my favorite pedals (especially for recording) is shown below:
It has a certain Yamaha vibe to it, although it's definitely not a Yamaha, nor any other "name" brand. The only words on it are "TAIWAN R.O.C." on a screwplate under the heel. It would appear to be from the late 70s or early 80s. Twin springs, direct drive, and an unusually high quality of fit and finish for a no-name component. Anyone have any context for it, or general thoughts on where it fits in equipment history?
