A slight aside, but a few years ago when I was tuning strictly aurally a potential customer called to inquire about my services. He asked me if I tuned aurally or with an ETD. When I responded that I tuned aurally, he said "thank you very much but I am looking for someone who tunes with an ETD. So go figure.
