The first successful electronic instrument tuner was invented and patented by Conn in or around 1936 IIRC.

We have quite the compendium of recorded musics in which we can hear perfect tuning examples throughout.

I can't recall ever witnessing the late Joe Pass using an electronic tuner, as one example out of probably hundreds, if not thousands.

That does not mean that one should not own or use a tuner.

All I do is try to encourage everybody to use the tuner as a method to better train the hearing abilities along those lines.

I don't like depending on "crutches" exclusively, but I also firmly believe that there is indeed a time and a place for everything, including the electronic tuner. For example, if confronted with a huge arena, likely a good idea to plug directly into that tuner...
