Well, I think there are two options how you could use the Tremolo Switch. Henning for example, who made the introduction video, obviously has a different approach to using the Tremolo Switch than I do. He wants to have engaged the Tremolo switch permanently, even in standard tuning. When you want to do that, the plunger have to push a little against the trem block, otherwise it would rattle. I myself engage the Tremolo Switch only when I want to go Drop D. I have set the Tremolo Switch so that there would be rattle in standard tuning, but when I lower the E String, there is enough load on the plunger, so that the rattling disappears. If you want to do so, you don’t need any preload on the Trem Block (in standard tuning). This means that you can set the Tremolo Switch just right so that you don’t have to retune the other strings when you go to Drop D. How to set this up properly is described in the Instruction Manual.
