well if it doesn't work for me - I'll let you know, or if it does.

Whist I would never use such a device for recording - obviously a full retune withthe whole lenghth of string to play with is the best option. however, it did occur to me that I had found a way of going from standard to C just re-tuning two strings and as such it was worth a go.

I have avoided open tunings for too long - they haven't been worth learning because I couldn't re-tune onstage without a lot of palaver.

However playing the variax guitar in pubs gave me an idea of what I was missing out on. Its not a gimmick as far as I'm concerned - if I can find a solution to a practical problem, I'm going to give it a go.
