Hello Mr. Fujita,
I am doing the bending technique with C Major and E major scale (2nd string).
I close my eyes to hear the sound first and then I check my tuner to see if I hit the note correctly. Do you think adding this tuner to check result is good idea?
Great question! I used to do that a little but you use your eyes to check things so I found it's too much! Best to do is bend note a few times slowly and check with a real note / pitch by ears.
