The Schaller tuners of the same era, (or shortly after) are my favorite vintage tuners, for both bass & guitar. They do the one thing a tuner is suppose to do, stay in tune! Not as pretty as a kluson, but much more reliable. Things that are designed to only do one thing, and do it badly make me irritated. Like a toilet that doesn't flush, or a vacuum that doesn't suck. I also have a pair of Schaller Strap Locks for every guitar I own, (except a couple acoustics). Except no substitutes!! I believe that Schaller made the "harmonica bridge" that was used on the early '70's guitars also.
P.S. I just surfed around a bit, trying to find some reference to Schaller producing the Tiltomatic Bridge and came up empty handed, I recall seeing replacements in Schaller boxes many moons ago, but I don't want to blame a fine German company for such an atrocity, based only on my poor recollection
