Hey! I bought a keiki mini uke roughly half a year ago and weren't playing it that often (it's too small for me, but a cute and great one ). Now i tried it again after i while and i can see that it is not tuned correctly on all of the frets. Even though its perfectly tuned on empty strings, whichever fret i press it'll be ~15 cents too sharp. I guess neck got bent a little when i wasnt using it? Is it fixable in any way, maybe its not a neck problem, has anyone had similar problem or any problem with the same uke? I really need to fix it, this ukulele is too cute to just throw it away
