Hi Peter Bro10,

It's a bit weird to me that you'd have trouble with the tuner with this. The pitch of the strings on any guitar (irrespective of string length) depends on two things: the thickness of the strings (actually the mass per unit length) and the tension (which is what you're adjusting when you twist the tuning pegs. The size of the guitar (length of the strings) should not matter at all, unless the guitar and strings have been designed to be tuned to a different key (which would be a very bad design because it would lead to confusion for someone with a good ear for pitch).

The only thing I can think of is the tuner. Have you checked it's battery? Have you used it recently with your full-size guitar or are you remembering that it worked once-upon-a-time? If you're sure that it works now with your full size guitar, perhaps it's a problem with the amplitude (loudness) of the sound coming from the smaller guitar. The tuner may not be sensitive enough to pick it up unless it's held very closely to the sound hole.

one more possibility: if the strings are way off from their proper pitch, the tuner will also be of little use. Try tuning up your full-size first, use your ear to get a rough match between that and the small guitar, then try the tuner again and see if that helps.

I have had luck myself getting one of those little things tuned up once for a niece, so I know it can be done. Good luck. I hope this helps
