I too have a small hand , or rather a large palm but short fingers.

I searched around for years, till finally I came acrossa Giannini.
This is a Brazilian saple wood guitar ; usually the company make classical guitars, but occassionally you can find a steel/folk version. Not only is the action very low, the neck is narrower than usual, and the back of the neck is slightly flat.

I have used and abused it for years. It can be temperamental, quite intolerant of different string makers gauges, but when the right set is found it is a lovely sound. It has a deep tone in the bass yet a light touch in the trebles ; and as a bonus, the head is usually carved, with the machine heads hidden backwards, classical style.

Unusual, difficult to find, but worth the effort.

Where are you in the West Country- in England's West Country ?- I have relatives down that way.
