I have an old Gibson catalog from like 1936. Maybe somebody here will know more about some of the questions this thing was raising for me. Does anybody know what is/was the deal with the old mona-steel strings that gibson used to sell? From what I can tell, the wrapping on them was something called monel, which the internet says was a 70/30 alloy of nickel and copper. This sounds pretty close to gypsy strings, right? Anybody ever play these or have any experience with them? The mona-steel strings were actually the featured strings over the bronze strings. I guess I was wondering if these strings are just gone now, or if they were really basically the same as nickel guitar strings or something else. Also kind of funny was that there were only two different 'weight' of strings--those with a wound B string and those without. I can only imagine what the gauges of the set with the wound B were.
The other question that I had was related to what appears to be a premium subset of the mona-steel strings, labeled 'hand-polished' and costing more. The only thing I can think of was that these may have been flatwound or something, but that is just a total guess. Anybody know anything about these? It may be noteworthy that this is the first Gibson catalog that had electric instruments in it, so that may have something to do with what strings were featured.
