1 Guitar Libido 1 year ago Has anyone tried one of these bridges? It seems like it would be a good mate to a Bigsby-equipped Gretsch. The specific model is the TP6R. Here's the skinny: "TonePros announces the introduction of the new "TonePros Roller Series" of bridges. These new bridges provide superior performance on trem equipped guitars such as Bigsby and others. The TonePros patented system locks the bridge solidly in place, which allows for the strings to return exactly in tune when trem'ed. Bigsby users will love this newest TonePros item, as it will allow them to use their trem often without the worry of going out of tune."
