Righty ho i will type up the problem
basically i found a thing on the internet saying put a wedge under the back then tune up the guitar and take the wedge out
i have done that various amounts of times and everytime i do it i take the wedge out and tune it but i find and i tune it the back bit slowly goes down making it basically untuneable becuase the tension in the strintgs is constantly changing and the string always seem to be too low so they don't ring properly or even play a different note when i put my finger on a fret
umm thats the best way i can explain i really
cheers
