I have just bought the blue mahalo uke guitar [nice colour].The vendor suggested tuning it to G,C,C,E,A,A.Which was said to be normal 6 string uke tuning.But in view of the neck width this involves very difficult left hand fingering as the nuts not set up in double courses like a mandolin etc. The strings on the instrument received appeared to be for the above tuning,but this vendor also said it could also be tuned in standard guitar tuning[as you will appreciate not with these strings it couldnt]SO,as I wanted to tune the instrument in normal six string guitar intervals I have strung it with D'ADDARIO pro.art classical guitar strings ej44's [VERY HARD TENSION] Tuned a full tone higher than standard ie.F#,C#,A,E,B,F#. from high to low,just like capoing on the second fret in standard tuning.IT SOUNDS GREAT!and chord transpositions are simple.Its a nice little instrument, seems correct in tone up neck and sounds great played fingerstyle.HOPE THIS HELPS....JOE MCTURK
