Hi everyone, please forgive me for sounding completely clueless. I read many tuning questions but still cannot determine my issue (brand new to music). I purchased a Pono Concert (MCD) strung with Ko'olau Alohi Low Gs. I took one lesson prior to getting the Uke in the mail and he showed me how to tune his instrument. However, I cannot get the tuned to G C E A. In fact, I can't get any of the strings tuned this way. I should have taken a baseline when I took it out of the box because it sounded beautiful... now it sounds like a dying dog. I thought it may have been the Oahu tuner so I swapped it for a Snark. Same issue. The problem is me. Can someone with these strings help a newbie--my music teacher is out of town for several weeks. Thank you for your help.
