Tuning a guitar using and Equal Temperament method

[Paul Chick (Earthlink)]

Subject: OT:Tuning a guitar using and Equal Temperament method

I tune pianos aurally and also play classical guitar. I would be  
interested to hear from any tuners who also play guitar and need to  
tune same whether they think there is any merit to the following  
method of tuning a guitar.
Thanks in advance.

Thanks for the post.  I play guitar and tune pianos, also.  When guitar
tuning, I've been listening to the open strings i.e. E 6th against the A
5th, for a beat (every 2-3 seconds) to be narrow; then the A to the D, etc.
I haven't taken the time to work it through for a complete tuning yet.  I'll
give your method a try.
