Trem Block Allen Bolt

[W.Suitor]

Could anyone enlighten me on the purpose for the single little allen bolt on the side face of an EBMM tremolo block? It's not the trem bar adjuster one, but the one way down the side of the block! Any info would be greatly appreciated.

Are you talking about Floyd Rose?

 

[Colin]

can you post a pic of what you mean?

No, it's not a Floyd, it's just a standard MM vintage trem. Thanks.

Yep, it's all here

Dan: I did a quick one for you and the others out there.

A= Trem Bar Tension Adjustment (spin control)
B= Bar Spring Mounting Screw.
C= Bar Spring (this is what the notch in your trem bar hits to keep it in the trem)

For those with piezo, your piezo junction board is mounted on the opposite side.

CORRECT. You shouldn't have to mess with B and C. Use A to adjust how freely you prefer your whammy bar to spin around.

I would think that it adjusts the depth of the trem bar to make sure it contacts the locking spring at the correct spot.

CORRECT. The original screw in question allows the user to adjust where the "final" position of the whammy bar rests in order to locate it in the ideal position for the bar spring ("C" in attached picture). If the screw is in too far, then the whammy bar won't snap in; if the screw is not in far enough, then the bar will be able to move in and out because the barspring is not aligned with the slot on the whammy bar.

Hope this answers everyone's questions.
