All guitars equipped with a Bigsby B5 or B7 vibrato suffer greatly from reduced frequency response and sustain because of the complete lack of quality of the front roller of the units. Callaham's upgrade kits provides a solid, stainless steel front roller and axle that will greatly widen the frequency response and sustain. The roller is polished to a mirror finish and is grooved to maintain string alignment. This is a simple retrofit and pays huge dividends.

Not for licensed or import Bigsby-style vibratos.

Nice upgrade.

The shaft did not fit in my brand new sand cast B7. I did not break out the micrometer, but the two shafts appeared identical to the naked eye. I installed the Callaham roller on the Bigsby shaft.

We've done this particular upgrade on a bunch of B5s and B7s, as we sell these complete bridges with all upgrades installed. Sometimes these small shafts are a bear to get in, but we're always able to - we have a little H-frame press that we use when one is stubborn. The fact that they ultimately always go in indicates that the shaft properly fits the hole, but it's only slightly looser than a slip fit, so any small obstruction will prevent it from being easily pushed in with finger pressure. Two possible causes: 1) the two holes on the outer frame are not perfectly in line with each other; 2) there's a burr where Bigsby has drilled and tapped a hole for the setscrew that holds the shaft in.

95% of the time or maybe more, we can push the shaft in with just finger pressure, but now and then there's one that is just too tight, in which case we go to the press, and that always does the trick. Tapping lightly with a plastic or brass hammer should do the trick for those who don't own a press, but we wouldn't suggest hitting the shaft with a steel hammer, as you might bend or deform it. In any case, sorry you had trouble with yours!

Great Product

This is my second "roller." It's a great product for many reasons, starting with quality and build.

Great idea

I purchased the Tone Shaper lined roller for my 2018 Fender 72 telecaster custom w/ a bigsby. I've also added a Vibramate string spoiler. These two inexpensive mods have made this guitar's playability go from very good to wonderful! Hey Fender, take note.
