they’ll be around a while, most likely. i personally know of two shops here in town that have had the same russian muff on the shelf since the bass big muff came out – people want the reliable switching, the direct signal blend, and the smaller casing.
i still see NOS sheet metal small stones around, in the wooden box no less, so i am guessing you have at LEAST a few months before you have to resort to ebay to get your hands on a soviet big muff.
