A nondescript chromatic tuner.
When I was scrambling around to get a cheap tuner somehow, I happened to find one for sale at a certain music store in Ochanomizu at a low price, so I bought it immediately.
I thought that even though it was a used model and a model that was out of production, I could use it without any problem, but when I set the low E as per the tuner, I felt that something was out of tune. ......
Lost my job due to the introduction of PolyTune. I am now thinking of a solution because I am concerned about the fact that the sound of Low-E is not right and it is not a true bypass.
