Celebrating my 2 month anniversary of getting my custom orchestra tuned Nonslider. I absolutely love it! The extended range on the low end is great. I have had my first Nonslider (regular tuning) since July, 2020.
These chromatics are so easy to live with with; no valve issues or slide issues. The orchestra tuned does have a couple of valves on the lowest notes, but so far, no issues there. I often just pick up the harmonica and start playing, so I really appreciate that I can play it from cold.
I have had difficulty learning to play melodies, that I already know, with sharps, but I am finally there. I had great difficulty when starting to play a harmonica, with learning to play single notes and I still can not play with pucker. I think most people will not have the difficulty I had when using a Nonslider. Also, I have not yet worked on learning a new melody, that has sharps, with a nonslider and believe that when I do it will be much easier than learning to play a melody that I already know, with respect to playing the sharps.
By the way, my orchestra tuned Nonslider's temperament is "compromised" and my other is "equal temperament." I don't think I can tell the difference.
