leeneia - what a coincidence, only yesterday I was googling the pros & cons of 'Jumbo' Frets.
I'll take a look at that link, thanks.

Big Al - my memory has become shocking bad this last 5 years or so.
[and I've been sober most of the last 3 years...???]

I'm pretty sure I only phoned the MU in the hope they could advise and provide any relevant phone numbers,
to seek further info.
So it would have been a pleasant surprise that they so helpfully offered me, a non member, a free specialist Drs appt.
