"I am an end user and Hammond Organ Co artist. I have used these switches for several year without any issues. They are bullet proof and very affordable. I have used them when I had a C2 Nord and now use them on all my Hammonds. (SK1, SK1-73, SK1-88, SK2, XK5, A3 Heritage and both Leslie 3300s) Bruce knows what he's doing and his product is outstanding!!"
