Hi Paul
Thanks for your tips and encouragement. There's been a bit of a development since my first post. Since yesterday I have a brand new acoustic guitar as the guitar that my husband and his Dad restored so beautifully has a slight problem with the bridge and needs further work.
It is missing some support inside so that the tension of the strings has caused the bridge and therefore the strings to lift. Although it is still playable it was slowing down my progress as I needed to use a lot of very precise and hard pressure to get the notes to sound cleanly and chords were impossible. The new one is a lot easier although naturally I still have a long way to go. I'm still keeping the restored instrument as it looks fantastic and is fixable but I'm practising on the new one now. At least I've built up some super strength in my fingers in the last days.
All the best
Rosemary
