Callaham Upgrade Kit, Bigsby B5/B7 Front Roller

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

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.

I’m an engineer, so quality and precision are key to me. This piece meets my expectations and improves functionality and purpose.

This roller is well machined and substantial. The bearings will probably last a lifetime. Having the guides is very useful. String alignment was always a problem for me with the stock roller. The guitar I put this onto has always been fairly stable with tuning, so I'm not sure if I'll notice a big difference there. But for folks with Bigsby tuning issues it will likely help. I did some other changes with strings and setup and the same time as installing this. The guitar sounds better, but not sure how much is from the roller and how much from other changes. Even so, I'm sure the density and guides of the new roller have a positive impact on the tone over the old one.
