The Vibramate Super Grip is custom made specifically to fit the arm of your Bigsby vibrato. The textured design adds contour to the overall grip and a soft comfortable feel for subtle vibrato techniques. The Vibramate Super Grip easily slides onto your existing Bigsby vibrato arm without any modifications or special tools. The tapered design ensures a snug fit once installed but can be removed just as easily by sliding it back off. One size fits all - Vibramate Super Grip fits all Bigsby vibratos using the standard stock flat arm including Import and Left-Hand models. Made in USA.
