Seems like people are starting to use these little 1- and 2-deck 12-position rotary switches but I can’t find a data sheet, manufacturer, dimensions, or even an image outside of these two attached. Anybody got any info? The larger versions are common on Ali, eBay, et al….but I need a small footprint. Price difference between these and Grayhill 71 should be significant. Could be a real resource for anyone stuffing a full-feature EQ into a 500-series package….
