I wish there was a string company that only packed balanced sets and presented their products according to average tension. Also making single strings available for further customization, but the actual sets are balanced.
Typical types, Roundwounds, Flatwounds, Tapewounds in a bunch of configurations. Stainless Steel, Nickel, Nylon.
A line with the target of 35lbs of tension could have gauges 0.135, 0.100, 0.075, 0.055, 0.042, 0.030, 0.021 plain and package sets of
Low 4 BEADG, standard 4 EADG, high 4 ADGC
Standard 5 BEADG, high 5 EADGC
Standard 6 BEADGC, high 6 EADGCF
Standard 7 BEADGCF
Name them according to tension, type, tuning and string count. 35NR-S6 = 35lbs per string, Nickel Round Wounds Standard Six, while 39SF-S4 = 39lbs per string, Steel Flat Wounds Standard Four.
If they offered a 35lbs, 37lbs, 39lbs, 41lbs lines at first (lighter for the Tapewounds) , in the above mentioned configurations then I think most people would be covered. Later if it was successful, you could introduce a higher tension line, half-rounds, perhaps even a Picollo line because that means you could offer double and triple course sets.
It'd be easier for the consumer, the solution to common issues.
"My 35SR-L4 set feels a little bit light for what I play, I'll get the 37SR-L4 set",
"I want to try flats that are similar tension to my 39SR-S5 set, I'll get the 39SF-S5 set",
"I am finding the feel of these 41NR-S4 set far too tough on my hands, I will get the 37NR-S4 set"
"I want to try tuning my five up a fourth but I am so use to my 39NR-S5 set, I'll get the 39NR-H5 set" etc.
Now that would be amazing, perhaps I just came up with a viable business plan, don't really know about making that reality, but first I guess some market research.
Who would be interested in a company that presented sets according to tension, produced balanced sets, in varying string types, and configurations?
Printed on the back of the packet a 7 column table with the tension for the intended tuning in the center in bold, the resultant tension of tuning up or down by a minor second, major second and a minor third printed either side of center.
