Thanks guys ,you have all been a big help and all are valid answers, and for that I thank you. I have had the guitar set up professionaly and the action set low, I also know the the intonation is correct. The strings are probably due to be change soon. The problem does go away if played with a lighter touch. As I am very heavy handed, playing lightly is going to be a challenge, as all beginners know so is learning to play the guitar in general. I am going to persevere with the light strings and see how I go. I really appreciate having the back up to be able to ask the questions on here, I will let you know how if there is any improvement in a few weeks time.

Thank you all,

JohnGC
