Hi Guys
As i have already metioned, i have brought this Guitar (Yammy F310) back, as i didnt find anything better for an exchange and i was not given the Money return too

.
But the store people had adjusted it for me, He first sanded the saddle and then did a few adjustments to the Truss rod too. Now again the action is higher when tune it to concert pitch !!!
I have also tried to check the relief, as UGB has mentioned (ie fretting the 1st and 16th fret of E string and inserting 2 business cards at the 7th fret) and the relief is actually almost exact, ie the business cards fit exactly !.
Now the problem is not with the saddle, neither with the neck, then what ???

Is it the nut ??? any ideas guys, sorry if i'm pestering you all a lot.
Please
Kindest Regds and Care
