[Electronics-Talk] guitar tuners for the blind

[Michael Micallef]

hi friends,

i have a blind friend of mine who is a guitar enthusiast, now he would 
like to guy a guitar tuner so he can setup the guitar cords himself 
without sighted help.  does anyone knows if such accessible guitar 
tuners exists?  if yes, from where can be bought?  any information that 
points hin into the right direction is highly appreciated.

thanks very much,
