@DoubleMIDI I was looking at your Dropbox chart and I notice the string gauges for the Spiro 3885 Mittle set are crossed out. I know the tension is a little higher but are the gauges the same? I would like a little oomph on the G and E on my Kolstein travel bass and was thinking of trying those out now that I know that I can get singles from Gollihur.
I think you refer to the baen.tamu.edu file that I have corrected regarding tension data.
The gauges are the original data from the source at baen.tamu.edu that no longer exists.
I have tried to keep the original data as it was but striked through if it was wrong(-ly calculated) and added in square brackets my corrected data (with a comment reference at the end of the group or row).
I had collected gauge data from talkbass, but never found the time to put something together. I also feel that that might better be made by the community by getting a cheap micrometer and each of us could measure their own strings and put it in a shared spreadsheet. But I even didn't find time to set up such a thing and there is data that should be collected and prepared before.
I just had a look at the chart.
The original gauge data was identical to the S42 set, so I assumed that the data was accidentally taken from the S42 set because it is more common in the USA. But since I was not sure, I striked through all that data because I couldn't proof the validity of the data for either of the sets.
See reference 16 and references 29 and 31 in that chart.
I know the chart is not that intuitive to read, but I kept it as it was and just added my stuff the way it was originally designed.
I have a 3885 medium set and could measure the gauges with a micrometer, but that might not happen before Christmas (and probably not before the new year).
Personally I'm not so much interested in exact gauges, so I'm not that much interested putting a lot of time in that. Maybe I have a file somewhere where I put some measured gauge information. I get back if I find something.
I have several projects that I prepared to start that didn't happen during the last ten years, so there is a lot to work on for me if I can find some spare time.
