KoAlana concert made of Sapele made by KoAloha. Resonsive, lightweight, balanced simplistic beauty. It's my "best friend" uke, quality time together and always feels good. I even forgave her for misbehaving after the amazing KoAloha company fixed her with their "better than the weather" warranty. It was like sending her away to reform school. "I had to", because she was misbehaving so badly but resulted in improved performance. Never underestimate what a skilled luthier can do for your instrument.
But my Mainland mahogany concert usually comes out to jams because the high g chimes above guitars and other instruments. This one has the most surface scars because I play her with wild abandon.
