100% aural, always have been. I might buy an ETD if my hearing in octave 7 starts to fail. So far, my hearing has survived, in spite of light tinnitus and a tendency for my left ear to rattle when sounds are loud. I use the earplugs a lot, but usually not for tuning, unless the top octave is very loud and harsh. Then I'll use them, but later check my work without them. I just enjoy the unencumbered way of tuning, and it seems to work for me. Susan
