Trem-Arm Tension Spring
Your tremolo arm stays put—no more flopping around. A quick, simple solution to a problem that can drive you crazy!
Screw the tremolo arm out of your bridge and drop the 4mm ball bearing in the hole. Drop the spring in next, and screw the arm back in place. That's all there is to it.
Turning against the ball bearing keeps the spring from binding as it compresses under the tremolo arm. With the added spring tension, the trem-arm stays wherever you leave it.
Works for traditional Stratocaster tremolos with "screw in" Tremolo Arms. Doesn’t work for our "Push or Pop" in Tremolo models.
Dimensions
Spring: 0.5" long x 0.150" diameter (12.7mm x 3.81mm)
Ball Bearing: 0.158" diameter (4mm)
