I have a hard time picking up the higher notes, however learning that you can attatch the clip to the actually action part is something I am going to try. I clip the korg to the upper part of the soundboard in the back of my troubadour Lyon and healy. Sometimes that helps, but mostly I end up plucking the high notes over and over till i get a register. I think the Korg is a wonderful tuner and I highly recommend it. It picks up other instruments, noises very well and is very sensitive.
