Thanks Deb - I saw your guitar at Broadstairs and have been trying to find outwhat it was ever since.
I own a Washbourn Travel Guitar which, although it has not got the quality of sound the contributors to this thread talk about, it is very compact and easily fits in a planes overhead luggage compartment. I use it mainly when my normal instruments are just too bulky to carry about. I also have a small 5 string banjo which is tuned to open A and is great for carrying about on planes.
