cheers, Mark.
Yeah man I agree the action on my JS1-A was brutal on the top 3 frets of course I wasnt smart enough to pull the nut out and sand the bottom... I cut deeper on the top... Same result tho plays a sh*^t load better. Nice buttery action now almost like a bought one and doesnt go sharp on the top 3 frets
