I love my knee control on my 301 Singer. A friend built the cabinet and put the foot control inside the cavity and made a lever to make it work with my knee. The reason he did that was I was used to using my knee on my mother's machine; I think it was a New Home, or something like that.
That controller needs work no matter where it is.
