I just purchased a Kala KA-FMT tenor from HMS. I had them set it up with Worth BT low-g strings. I liked the Worths so much I decided to put a high-g set on my KA-T (purchased from HMS about a month ago, but with the stock Aquilas). This was the first time I ever changed strings. The high-g strings I put on my KA-T feel way tighter than the low-gs on the FMT, like the tension is greater. With the exception of the G strings, the gauges are identical. Could I have done something while installing the strings to increase the tension? Or is it just the difference between the two ukuleles? I love the sound of both, but the difference in the feel of the strings is very noticeable.
