I HAVE BEEN SITTING IN FRONT OF THE FIREPLACE for three hours tonight playing one after the other of the new tenors. I pick for a while, I strum for a while, then I change ukes again. It is fascinating, each has a different voice, and as I play them I hear them mellowing, the picked notes becoming clearer, truer. You could almost think that they are living things slowly coming to life. I have experienced it so many times and yet I always marvel at how an instrument responds to being played. I am sure that part of it is the strings settling in but I think the instruments settle in as well. The A string on one of the ukes seemed a little shrill to me. The tuner said it was right on "A" but I was not pleased with the sound. About half an hour ago it changed, I did nothing but play it, Now it is perfect. I have put identical strings on these instruments, Southcoast heavy medium linear/with round wound bases. Wonderful strings, yet these ukes are each individuals. I am delighted with each. I cannot decide which I like best. Guess that makes it a successful build.
