My HF-1 went from the factory to its original owner's closet---where it would sit unplayed until advertised on craigslist seven years later. It was still perfectly set up when I tried it out. After six months, playing everyday, I wouldn't change anything about this amazing ukulele. Welp, anything other than the strings once in a while.
Which reminds me: Dang, these Ko'olau Mahana strings sound terrific and feel great on this Kamaka. So deep. So mellow. So good.
