By the way, while we are on the subject of these lower tunings, let me point out one more thing.
I think sometimes people get a little worried when they see a name like "Heavy Gauge" ukulele strings - they worry that these may put an undue strain on their instrument.
It's true that if you put on a set of these and tuned them, for example to key of C tuning on a standard concert, you would, indeed, have a very tight set of strings.
That is not their purpose. They are designed for lower tunings. Normal strings would be too loose to tune down - tension would be unplayably low.
These "Heavy Gauges" (ours or anybody's), when played at these lower tunings, have nearly the same tensions as a typical concert set designed for C tuning.
