Well, as a newbie I may have put too large of strings on the cheap kids guitar and broke the knobs on the original. My daughter has gotten interested in playing it, but I didn't want to spend more on parts than the value of the guitar. I looked around, took some measurements, and ordered these. Perfect fit, I didn't even have to redrill the holes. These came with sleaves which the original guitar didn't have. I drilled out the neck to fit the sleaves as it looks like it would provide better support than the original shaft on wood. Fit perfectly. Put light weight strings on the guitar and tuned it up. Tone sounds great----now we just need to learn how to play it correctly :-)
