I have been using this on my Shobud D10 pedal steel guitar. With 10 strings per neck, 8 floor pedals and 9 knee levers so there is a lot to tune! I'm using the SE9 sweetener for open strings and the SP6 for all of the pedals and levers and it does an amazing job and was so easy to set up.
I set my setting so that I can use the sweetener for the open strings first and directly under that setting is the sweetener for the pedals and levers so even when I'm in a hurry it's a breeze.
I've used a tempered tuning for years with a tuner that roughly showed the cent values and it got close but it took a while and always had to be tweaked.
This I'm telling you is the bomb and I have no idea why I waited so long to get the real deal.
This model came with more sweeteners than I will use but since I also play bass, lead and dobro I'm loving it for those as well.
I just ordered the bracket to mount this to the leg of my steel guitar and I got a real person who gave me the feeling she could be family. Buy it and your welcome!
